What you get
Built by a learner, for learners
Everything one IELTS learner actually needs
Full listening and reading mock tests
Sit complete listening tests with real audio, or reading papers with the passage beside the questions as in the real exam. Both are timed and marked for you, with a band estimate the moment you finish and the exact questions you slipped on.
Drills that fit a busy day
Short, focused practice for spelling, True/False/Not Given reading, error correction, and vocabulary recall — small enough to finish in a break, frequent enough to actually stick.
Progress you can see
Every test and drill is recorded against your account, so you can watch your listening score climb instead of guessing whether the studying is working.
How it works
Three steps to exam-ready
01
Find the gap
Take a mock test or a quick drill. Your first score tells you where the real weakness sits.
02
Study the fix
Follow the connected notes for that skill instead of reading everything in a random order.
03
Prove it stuck
Return to practice, watch the score move, and repeat until the skill feels automatic.
What's inside
All of it free with an account
Four places to study, one account
Note library
Grammar and vocabulary notes
Sentence structure, tenses, articles, prepositions, linking words, collocations, and the error patterns that quietly cap your writing band. Every note is a page you can read, save, and return to.

Out of 40 questions
IELTS listening score to band conversion
IELTS listening is marked out of 40, and the raw score converts to a band from 0 to 9. Every mock test in Band 9 Vault scores you on this scale, so you always know how far the next half-band actually is.
| Correct answers | Band score | What it means |
|---|---|---|
| 39–40 | 9.0 | Expert listener — almost nothing slips past you. |
| 37–38 | 8.5 | Very high accuracy, occasional spelling loss. |
| 35–36 | 8.0 | Strong enough for competitive university entry. |
| 32–34 | 7.5 | Above the bar for most postgraduate courses. |
| 30–31 | 7.0 | The common requirement for study and migration. |
| 26–29 | 6.5 | Solid, but distraction and paraphrase still cost you. |
| 23–25 | 6.0 | Meets many undergraduate requirements. |
| 18–22 | 5.5 | Detail and spelling are the usual leaks here. |
| 16–17 | 5.0 | Foundation work will move this fastest. |
| 13–15 | 4.5 | Focus on vocabulary and number/date recognition. |
These bands are the widely published conversion for IELTS Academic listening and are used here as an estimate. Your official band comes only from a real test sitting.
Who it helps
Built for people preparing alone
Self-study candidates
No coaching centre, no fixed schedule. You need material that is ordered for you and practice that marks itself, because nobody else is going to check your answers.
Retakers stuck on one band
You already know the test format. What you need is to find the specific skill holding the score at 6.5, and drill it until it stops leaking marks.
Working and studying learners
Preparation has to fit around a job or a degree. Short drills and saved progress mean a ten-minute session still counts toward the target.

About Band 9 Vault
Band 9 Vault is a free, independent study site for IELTS Academic. It exists because IELTS preparation is usually scattered across a dozen places: grammar in one book, listening audio on a video site, vocabulary in a notebook, and no record of what is actually improving.
What it is
Everything sits in one place and is connected. Study notes cover sentence structure, tenses, cohesion, vocabulary, punctuation, and the errors examiners notice most. Full listening and reading mock tests run on the real clock and mark themselves the moment you submit. Short drills cover spelling, True/False/Not Given reading, error correction, and vocabulary review. Every result is recorded, so the site can tell you where you actually stand rather than where you feel you stand.
Who it is for
Learners who are somewhere around Band 6 or 6.5 and need to reach 7 or higher, especially those studying alone without a teacher to mark their work. The material assumes you already speak some English and want the specific gaps closed, not a beginners' course.
Where the material comes from
The study notes are written for this site. The practice papers are collected from publicly available IELTS practice material so that learners have enough papers to work through; they are for private study only. If you own material used here and would rather it were removed, write to us and it will be taken down.
What it is not
This is not the official IELTS test and not an official practice product. It is not affiliated with, endorsed by, or connected to the British Council, IDP Education, or Cambridge University Press & Assessment, who jointly own the IELTS trade mark. Band scores shown here are estimates for practice, not official results.
What it costs
Nothing. There is one plan, it is free, and no part of the site is held back for a paid tier. An account exists only so your results and saved notes follow you between devices.
Common questions
Everything learners ask most often, answered plainly. If yours is not here, write to us.
Does it cost anything?
No. Band 9 Vault is free to use, and no part of it is held back for a paid tier. An account exists so your scores and saved notes stay with you rather than in one browser.
Do I need an account to study?
You can practise as a guest, but results stay in that one browser and are lost if you clear it. Signing in keeps your progress on every device you study from.
Is this the official IELTS test?
No. This is an independent study site with practice material only. It is not affiliated with, endorsed by, or connected to the British Council, IDP Education, or Cambridge University Press & Assessment, who jointly own the IELTS trade mark.
Which IELTS module is it for?
IELTS Academic. The grammar, vocabulary, and listening material also helps General Training learners, but the writing and strategy notes target the Academic paper.
Are the mock tests timed like the real exam?
Yes. A listening test runs 40 questions with real audio on a 32-minute countdown, and a reading paper gives you three passages and 40 questions in 60 minutes. Both match the computer-delivered format and mark your answers the moment you submit.
How is my band score calculated?
Your correct answers out of 40 are converted using the standard IELTS band table for that paper — the listening table, or the Academic reading table, which is marked slightly harder. A paper with fewer than 40 questions is put on the 40-question scale first, so every band means the same thing. It is an estimate for practice, not an official result.
How long does it take to raise my band score?
Most learners moving half a band need four to eight weeks of consistent practice, and a full band usually takes longer. Steady daily drills move the score faster than occasional long sessions.
Where should I start?
Take one mock test before studying anything, so you have a real number to work from. The How it works page sets out the whole order, and why testing first beats reading first.
Can I use it on my phone?
Yes. The site works in any modern mobile browser with no app to install, and because your progress is tied to your account you can start a drill on a phone and finish on a laptop.
What happens if I close a test halfway through?
The clock keeps running against the original finishing time, and your answers are still there when you come back, exactly as the real computer-delivered test behaves. Only a submitted paper is recorded as a result.
An answer key looks wrong. What should I do?
Tell us. Send the test number and the question number to our contact address and it will be checked and corrected. Practice material collected from elsewhere sometimes carries mistakes, and we would rather fix them than leave learners doubting themselves.
Can I delete my account and my results?
Yes. "Reset my data" on your profile clears your whole study record straight away, and emailing us removes the account itself along with everything attached to it. The privacy policy sets out exactly what is stored.
How it works
Most people open a study site, read three pages, and never come back, because nothing tells them what to do first. Here is the order that works, and why.
Step 1 — Take one mock test before you study anything
This feels backwards, and it is the most useful thing you can do. A listening or reading paper takes under an hour and gives you a number. Without that number you are guessing at your own level, and learners almost always guess wrong in one direction or the other. Do not revise for it. A score that flatters you is worth nothing.
Step 2 — Read what the result actually says
After you submit, every question is listed with your answer beside the right one. Do not skim it. Go through the ones you got wrong and put each into a group: did you mishear the word, not know the word, misread the question, or run out of time? Four different problems, four different cures. Most learners discover that one group is far larger than the rest, and that group is your real work.
Step 3 — Fix the grammar behind the mistakes
The note library is arranged by what actually goes wrong, not by chapter order. If your errors are tenses, start with the tense notes; if sentences fall apart in writing, start with clauses. Save a note with the star and it waits for you on your profile. Reading a note you do not need is time you did not spend on the one you do.
Step 4 — Drill in short sessions, most days
Ten minutes of spelling, True/False/Not Given, error correction, or vocabulary review beats a three-hour session at the weekend. The vocabulary drill schedules each word to come back just before you would have forgotten it, so the words you find hard return more often than the ones you know.
Step 5 — Test again, and compare
After a week or two of drills, sit another paper. Your profile keeps every result with its band, so you can see whether the line is moving. If two papers in a row show no change, the problem is not effort — it is that you are practising the wrong thing, and step 2 needs doing again.
How long this takes
Half a band usually takes four to eight weeks of steady practice. A full band takes longer. Anyone promising faster than that is selling something. What moves the number is consistency: a short session most days beats a long one now and then, every time.
A note on the band scores here
The band you see is your correct answers converted with the standard IELTS band table for that paper. It is an honest estimate for practice, not an official result, and the real exam has pressures a practice paper cannot copy. Treat it as a direction, not a promise.

Reading Matching Headings Strategy
Before matching, answer: What is this paragraph MAINLY about?
Reading Matching Headings: Strategy & Mastery
Why Matching Headings is Second-Hardest Reading Type
Examiner Wisdom:
- Tests: Identifying MAIN IDEA (not just finding details)
- Band 6: Gets confused between main idea + supporting detail
- Band 7: Recognizes main idea but struggles with similar heading pairs
- Band 8: Systematically eliminates distractors
Critical Skill: Distinguish between:
MAIN IDEA (heading matches paragraph focus)
vs
SUPPORTING DETAIL (interesting but not the paragraph's purpose)THE PROCESS: 7-STEP MATCHING STRATEGY
STEP 1: Preview All Headings (2 min)
Before reading passages, scan all heading options:
List them: understand what each is about (general categories, specific topics)
Note: Are there similar headings? Group them by category
Mark: Any obvious distractors (clearly wrong for any paragraph)
Example headings:
A. Benefits of solar technology
B. Challenges in implementing renewable energy
C. Government subsidies for clean technology
D. Solar panel efficiency improvements
E. Companies profiting from renewable energy
F. Environmental impact of fossil fuels
G. Cost reduction in solar manufacturing
Grouped:
[Benefits/Positive] = A, C, D, E
[Challenges/Negative] = B, F
→ These are the "traps": similar enough to confuseSTEP 2: Read Paragraph 1, Identify Its Main Topic
Before matching, answer: What is this paragraph MAINLY about?
Paragraph: "Solar technology has seen dramatic cost reductions over the past decade.
In 2010, solar panels cost $3.50/watt; today they cost $0.50/watt. This price drop results
from economies of scale and competition among manufacturers. Scientists predict costs may
fall further as technology improves."
Main topic: COST / PRICE REDUCTIONS (not "benefits" broadly, but specific to COST)
Match to headings:
- A (general benefits) ✗ Too broad
- B (challenges) ✗ Wrong direction
- D (efficiency improvements) ✗ Different from cost
- G (cost reduction) ✓ EXACT MATCHSTEP 3: Identify Distractors (Words That Trick)
Distractor Type 1: RELATED BUT NOT MAIN IDEA
Paragraph: "Electric vehicles produce zero emissions during operation, reducing air pollution
in urban areas. Health studies show that children living in low-emission areas have fewer
respiratory problems."
Main idea: ENVIRONMENTAL/HEALTH BENEFITS OF EVs
Heading options:
- "Environmental advantages of electric vehicles" ✓ CORRECT
- "Manufacturing concerns for electric car production" ✗ Not mentioned
- "Children's respiratory health problems" ✗ Only supporting detail, not main idea
- "Urban air pollution solutions" ✓ Could match, but too broad; first heading is more precise
Key: The correct heading names THE MAIN TOPIC, not supporting detailsSTEP 4: Test Against "Too Specific" and "Too General"
Paragraph main idea: "Climate scientists debate whether human activity causes 30% or 70%
of observed warming. Recent models suggest the range is actually 40-80%, depending on
methodology."
Heading options:
- "The percentage of warming caused by humans" ✓ CORRECT (precise topic)
- "Climate change" ✗ TOO GENERAL (includes ocean rise, extreme weather, etc.)
- "The debate about warming percentages" ✓ Also possible (emphasizes debate)
- "Methodology in climate modeling" ✗ Too narrow (methodology is mentioned but not the focus)
Rule: Correct heading = specific enough to distinguish this paragraph from others,
but general enough to capture its main ideaSTEP 5: Account for Negation Reversals
Paragraph: "Despite over $50 billion in renewable investments, fossil fuels still dominate
global energy. Coal, oil, and natural gas account for 85% of energy production. Renewable energy
represents only 15%, far below targets."
Main idea: RENEWABLES FAIL TO DISPLACE FOSSILS / SLOW RENEWABLE PROGRESS
Heading options:
- "Rapid growth of renewable energy" ✗ OPPOSITE of paragraph meaning
- "Challenges facing renewable energy adoption" ✓ CORRECT (implies slow progress)
- "Benefits of fossil fuels" ✗ Not the focus (paragraph criticizes fossil dominance)
- "Future of renewable energy" ✗ Too vague; doesn't capture the "failure/slowness" angle
Key: Be alert to heading that SEEMS relevant but REVERSES the paragraph's messageSTEP 6: Use Process of Elimination
When paragraphs 1-5 are matched:
- Remaining headings for paragraph 6 = narrowed options
- Even if you're unsure what 6 is about, remaining headings may be obviously wrong
Example: You've matched A, B, C, D, E to paragraphs 1-5.
Remaining for paragraph 6: F, G, H
Paragraph 6 discusses "efficiency gains"
- F: "Cost reduction in solar" ✗ Already used for another paragraph
- G: "Efficiency improvements in renewable technology" ✓ Only option left
- H: "Environmental impact of fossil fuels" ✗ Wrong topic
Even if G isn't perfect match, process of elimination confirms itSTEP 7: Verify (Check Second Time)
Before finalizing, re-read paragraph ONCE more:
- Does the heading accurately name the main point?
- Could a different remaining heading fit better?
- Am I caught by a distractor (related but not main idea)?
If uncertain: Leave a note, move on, return to difficult ones LAST15 MATCHING HEADINGS DRILL SET
Drill 1-3: Clear Main Idea / Obvious Heading
Paragraph 1:
"The Internet enables instantaneous global communication. Email, video calls, and instant
messaging have replaced traditional mail and telephone systems. Business efficiency has
improved dramatically as a result."Heading Options: A. Communication technology throughout history B. Internet's impact on business speed C. Email vs traditional mail efficiency D. The history of technology innovations
Answer: B (Main idea: Internet improves business efficiency through communication)
Paragraph 2:
"Artificial intelligence has limitations. AI cannot understand emotional context, often misinterpreting
sarcasm and humor. AI lacks common sense reasoning, struggling with scenarios requiring contextual
knowledge. These constraints limit AI's real-world application."Heading Options: A. Limitations of artificial intelligence B. How artificial intelligence learns C. Applications of AI in business D. Sarcasm detection in language
Answer: A (Main idea: AI has specific limitations)
Paragraph 3:
"Photosynthesis converts sunlight into chemical energy through a complex biological process.
Plants absorb carbon dioxide and water, using solar energy to create glucose and oxygen.
This process sustains nearly all life on Earth."Heading Options: A. The importance of plants for oxygen production B. How photosynthesis sustains life C. The chemical structure of plants D. Solar energy conversion mechanisms
Answer: B (Main idea: photosynthesis as life-sustaining process)
Drill 4-6: Distractor Traps (Supporting Detail vs Main Idea)
Paragraph 4:
"Genetically modified crops increase crop yields by 20-30%, helping address global food security.
These crops require fewer pesticides, reducing environmental impact. However, scientific studies
confirm concerns about long-term dietary effects remain unresolved."Heading Options: A. Benefits of genetically modified crops B. Pesticide reduction through GMO technology C. Balanced assessment: Advantages and concerns of GMOs D. Food security solutions for developing nations
Answer: C (Main idea: balanced view of benefits AND concerns; not just benefits)
- Trap: A is tempting (benefits ARE discussed) but misses the "concerns" angle
- Trap: B focuses on one supporting detail (pesticide reduction)
- B is too narrow; C captures the paragraph's full scope
Paragraph 5:
"Renewable energy sources face intermittency challenges. Solar panels generate electricity only
during daylight; wind turbines require consistent wind. Battery storage technology could solve
this problem, but current costs exceed $500 per kilowatt-hour. Economic barriers prevent widespread
adoption of storage systems."Heading Options: A. Economic barriers to renewable energy storage B. How solar and wind energy work C. Battery storage solutions for renewable energy D. Intermittency problem in renewable energy systems
Answer: A or D (Both are reasonable, but A is more specific to MAIN POINT—the barrier preventing adoption)
- Close call: D describes the problem; A addresses why the solution isn't implemented
- IELTS typically prefers: Most specific heading that captures unique angle
- Answer: A (economic barrier is the paragraph's concluding focus)
Paragraph 6:
"The Amazon rainforest generates 20% of the world's oxygen. Its vast biodiversity includes
millions of undiscovered species. Indigenous communities have inhabited and managed the forest
for thousands of years. Deforestation threatens all these elements."Heading Options: A. Indigenous management of Amazon resources B. Oxygen production in the Amazon rainforest C. Multiple values of the Amazon rainforest at risk D. Undiscovered species in tropical regions
Answer: C (Main idea: multiple aspects of Amazon worth protecting)
- Trap: A, B, D each represent ONE aspect mentioned
- But the paragraph lists multiple aspects (oxygen, biodiversity, indigenous use)
- C captures the full scope: "multiple values... at risk"
Drill 7-9: Similar Headings (The Real Challenge)
Paragraph 7:
"Over 40% of food grown in developed nations is wasted. Retailers discard items with minor
blemishes. Consumers throw away perfectly edible food. This waste represents both environmental
damage and economic loss."Heading Options: A. Food waste in developed nations: causes and impacts B. Consumer behavior regarding food waste C. Retailers' role in food waste systems D. Environmental consequences of food waste
Answer: A (Main idea: multiple causes—retailers, consumers—plus impacts)
- Trap: B is tempting (consumer behavior discussed) but misses retailers
- Trap: C is tempting (retailers discussed) but misses consumers
- Trap: D captures one impact (environmental) but misses economic
- A is broadest correct answer: includes causes AND impacts
Paragraph 8:
"Artificial intelligence surpasses human capabilities in specific domains. Chess-playing AI defeats
world champions. Image recognition algorithms exceed human accuracy. Yet humans excel at
cross-domain reasoning, creativity, and emotional intelligence. Neither intelligence type is universally superior."Heading Options: A. Artificial intelligence superiority over human cognition B. Where human and AI intelligence differ C. Limitations of artificial intelligence D. AI performance in specific tasks
Answer: B (Main idea: comparison of human vs AI strengths/weaknesses)
- Trap: A implies AI is superior overall (paragraph says "neither superior")
- Trap: C focuses only on AI limitations (forgets human strengths)
- Trap: D focuses on AI performance (ignores human comparison)
- B captures the balanced comparison
Paragraph 9:
"Renewable energy adoption has accelerated globally. Solar and wind capacity has doubled in
five years. Investment in clean technology exceeds fossil fuel investment. Governments are
committing substantial funding. However, the transition remains incomplete; fossil fuels still
provide 80% of global energy."Heading Options: A. Government commitment to renewable energy B. Renewable energy growth versus persistent fossil fuel dependence C. The acceleration of renewable energy adoption D. Investment trends in energy technology
Answer: B (Main idea: renewable growth BUT fossil fuels still dominate)
- Trap: A addresses one supporting detail (government funding)
- Trap: C is true but misses the "still fossil-dependent" qualification
- Trap: D is vague, misses the energy-type distinction
- B captures the central tension: growth happening, but progress incomplete
Drill 10-15: Negation & Strategic Wording
Paragraph 10:
"Critics argue that remote work reduces collaboration and team cohesion. Employees working
from home feel isolated. Face-to-face interaction enables creativity impossible in virtual meetings.
However, evidence suggests remote workers are equally productive, with better focus."Heading Options: A. Disadvantages of remote work systems B. Productivity benefits for remote workers C. The challenge of remote collaboration D. Balancing concerns and evidence: Remote work benefits and drawbacks
Answer: D (Main idea: acknowledges concerns BUT evidence supports productivity)
- Trap: A emphasizes concerns (critics, isolation) but ignores evidence contradicting them
- Trap: B emphasizes only benefits; ignores real concerns
- Trap: C emphasizes only negatives
- D captures complexity: concerns are raised, but evidence suggests positives
Paragraph 11:
"Traditional education emphasizes rote memorization, preparing students for standardized tests.
Modern pedagogical research shows this approach develops surface-level understanding rather
than deep learning. Progressive education methods promote critical thinking and problem-solving.
These approaches require fundamental classroom restructuring but yield superior learning outcomes."Heading Options: A. Traditional versus progressive educational approaches B. The limitations of traditional memorization-based learning C. Benefits of critical thinking in education D. Classroom restructuring challenges
Answer: A (Main idea: comparison of two education types, with value judgments)
- Trap: B focuses only on criticisms
- Trap: C focuses on one aspect of progressivism
- Trap: D focuses on implementation difficulty
- A best captures the comparison and transition implied
Paragraph 12:
"Machine learning algorithms improve through exposure to data. The more data they process,
the more accurate predictions they make. However, data quality matters more than quantity.
Poor-quality training data produces unreliable AI, regardless of volume. Recent failures in
AI systems stem not from insufficient data, but from biased or incomplete training sets."Heading Options: A. The importance of data quality over quantity in AI B. How machine learning improves through data exposure C. Failures in artificial intelligence systems D. Bias in machine learning algorithms
Answer: A (Main idea: quality > quantity, with examples proving this principle)
- Trap: B is accurate but misses the key insight: quality matters more
- Trap: C addresses consequences but not the main principle
- Trap: D addresses one type of bias but misses broader principle
- A captures the central claim with supporting reasoning
Paragraph 13:
"Ocean acidification occurs when atmospheric CO₂ dissolves in seawater, lowering pH levels.
This process threatens marine ecosystems, particularly organisms with calcium-based shells.
Pteropods, plankton, and corals face dissolution of their skeletal structures. Recent studies
confirm that acidification has already begun damaging these populations globally."Heading Options: A. Ocean acidification and threats to marine life B. The causes and effects of rising ocean acidity C. Marine species vulnerable to acidification D. How carbon dioxide affects ocean chemistry
Answer: A (Main idea: acidification + results for marine life)
- Trap: B is close but "causes" framing may be misleading (process is explained, but emphasis is on effects)
- Trap: C too narrow (focus on species vulnerability, not broader process)
- Trap: D too narrow (chemistry background, not the main focus)
- A best balances cause-effect focus
Paragraph 14:
"Microplastics are tiny plastic fragments found in oceans, soil, and air. They originate from
breakdowns of consumer plastics. Alarmingly, microplastics now appear in human blood, lungs,
and organs. Health implications remain unknown, creating significant scientific uncertainty.
Governments debate regulation, while reduction strategies prove difficult to implement."Heading Options: A. Sources and distribution of microplastics B. Emerging concerns about microplastics in human bodies C. Health risks of microplastic consumption D. Government policy on microplastic regulation
Answer: B (Main idea: microplastics in humans + uncertainty about health)
- Trap: A addresses sources (opening detail) but misses the "human health" angle
- Trap: C assumesrisk is known (paragraph emphasizes uncertainty)
- Trap: D focuses on policy response (supporting detail)
- B captures the emerging concern + uncertainty
Paragraph 15:
"Urbanization has accelerated migration from rural to urban areas worldwide. Cities offer economic
opportunities, education access, and healthcare facilities unavailable in rural regions. However,
rapid urbanization creates challenges: inadequate housing, overwhelmed infrastructure, and
environmental degradation. Sustainable urban planning mitigates these problems but requires
long-term government investment."Heading Options: A. The migration patterns from rural to urban areas B. Benefits and challenges of rapid urbanization C. Urban infrastructure limitations D. Solutions to urbanization challenges
Answer: B (Main idea: urbanization attracts people BUT creates problems; solutions exist)
- Trap: A addresses one aspect (migration) but not the balanced benefits/challenges
- Trap: C emphasizes only challenges
- Trap: D emphasizes only solutions
- B best captures the complex reality: benefits attract people, challenges require solutions
FINAL MATCHING CHECKLIST
Before confirming your matching answer:
✓ Main idea test: Can you state the paragraph's main point in one sentence? ✓ Heading specificity: Is the heading specific enough to distinguish this paragraph from others? ✓ Supporting detail check: Aren't you matching to a supporting detail instead of main idea? ✓ Distractor awareness: Could a similar heading fit better? ✓ Negation check: Doesn't the heading reverse the paragraph's meaning? ✓ Process of elimination: Have you considered remaining options?
