A real grammar library
Hundreds of study notes covering sentence structure, tenses, cohesion, vocabulary, and the errors examiners notice most — written in plain language and linked together so one lesson leads to the next.
Band 9 Vault turns scattered IELTS preparation into one connected study space: structured grammar notes, full listening and reading mock tests with instant band scores, and short daily drills that keep your weak spots from becoming exam-day surprises.
Free to use · No card needed · Your scores follow you to every device
Hundreds of study notes covering sentence structure, tenses, cohesion, vocabulary, and the errors examiners notice most — written in plain language and linked together so one lesson leads to the next.
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.
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.
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.
Take a mock test or a quick drill. Your first score tells you where the real weakness sits.
Follow the connected notes for that skill instead of reading everything in a random order.
Return to practice, watch the score move, and repeat until the skill feels automatic.
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.
Open the library → How it worksTest first, read the result, fix the grammar behind the mistakes, then test again. Five steps that tell you what to study now and what can safely wait.
See the five steps →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.
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.
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.
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.

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.
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.
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.
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.
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.
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.

IELTS Academic. The grammar, vocabulary, and listening material also helps General Training learners, but the writing and strategy notes target the Academic paper.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

What This Looks Like:
Band 6: "There are many opinions on whether technology is helpful for education.
Some people think it is good, others think it is bad. I will discuss both sides."
(Doesn't answer the actual question; just lists opinions)
Band 8: "While technology offers substantial educational benefits through personalized
learning and global resource access, its implementation requires careful pedagogical
integration to prevent over-reliance and maintain critical thinking skills. On balance,
technology's advantages outweigh its limitations in contemporary educational contexts."
(Directly answers: position + key reasoning)
How to Fix:
BAND 6 mistake: Avoiding taking a clear stance
BAND 8 approach:
- If asked opinion → state clear opinion in introduction
- If asked discuss both → acknowledge both, then clarify which you believe more
- If asked solution → present your solution early
- Never write "I will discuss both" (just do it naturally)
What This Looks Like:
Question: "Some people think modern education should focus on practical skills
rather than theoretical knowledge. Discuss both sides."
Band 6: Starts discussing practical vs. theoretical, but by paragraph 3 starts
talking about: student motivation, how expensive education is, why homework exists...
Band 8: Stays completely within scope:
- Paragraph 2: Benefits of practical skills focus
- Paragraph 3: Benefits of theoretical knowledge
- Paragraph 4: Clear position and relevance
(Every sentence connects back to the core question)
How to Fix:
Before writing:
1. Underline the EXACT topic in the question
2. Write 1-sentence answer to each body paragraph
3. During writing: Check EVERY sentence = relevant to question?
What This Looks Like:
Band 7: "Technology helps education because it provides better resources.
Students can find information online. The Internet is useful."
Band 8: "Technology facilitates personalized learning pathways; students can access
specialized educational content tailored to individual learning speeds and preferences.
Furthermore, digital platforms enable real-time feedback mechanisms unavailable in
traditional classroom settings, allowing educators to identify and address comprehension
gaps immediately. This responsiveness accelerates knowledge consolidation compared to
conventional annual assessment cycles."
Why This Matters:
How to Fix:
For each claim, answer:
- WHAT is the argument? (what happens)
- HOW/WHY does it work? (the mechanism)
- WHAT'S THE IMPACT? (consequence or significance)
Weak: "Using technology improves learning."
Better: "Using technology improves learning BY enabling personalized pacing.
This matters BECAUSE students learn at different speeds, and individualized
instruction allows faster learners to advance while giving struggling students
additional consolidation time, RESULTING IN deeper mastery."
Band 6 Examples (Generic):
"For example, students can use computers to do homework."
"India is a big country where many people use technology."
"In my opinion, my friend told me that he likes online classes."
Band 8 Examples (Specific):
"Learning management systems like Moodle enable submission of assignments,
automatic plagiarism detection, and algorithmic distribution of grading tasks,
reducing instructor workload by approximately 40% according to university surveys."
"Countries like Singapore and South Korea have integrated AI-driven adaptive
learning platforms into national curricula, demonstrating 15-20% improvement in
standardized assessment scores compared to control classrooms."
How to Fix:
Weak: "People use technology in education."
Better: "Machine learning algorithms personalize content delivery, with
research from Stanford's Learning Analytics Lab indicating that students
using adaptive platforms demonstrate 30% faster skill acquisition."
(Specific + Demonstrated impact + Research basis)
Common Task 2 Grammar Issues:
| Error | Band 6 | Band 8 |
|---|---|---|
| Subject-Verb | "Technology and education is important." | "Technology and education are important." |
| Articles | "Education is essential for developing the skills." | "Education is essential for developing skills." |
| Word Form | "The improvement of education's quality..." | "Educational improvement..." (nominalization) |
| Tense | "Technology was changing how students learn." | "Technology is changing..." (present ongoing) |
| Passive | "It is believed by many that..." | "Many believe that..." (agency) |
| Prepositions | "Discussion about technology" | "Discussion of technology" |
| Fragments | "Which provides many benefits." | Connect to main clause |
| Run-ons | "Education develops skills students need them." | "Education develops skills students need." |
Strategy:
After writing, check EVERY sentence for:
1. Subject + verb agreement?
2. Correct articles (a/an/the)?
3. Correct word form (noun/verb/adj/adv)?
4. Right preposition for that verb?
5. Proper tense?
(Use [[Error_Classification_System]] for reference)
Band 6 Approach (Repetition):
"Technology is important for education. Technology helps students learn.
Technology provides many things. Technology is used by modern students."
Synonym count: "technology" appears 4 times in 4 sentences
Result: Sounds immature; Band ceiling = 6.5
Band 8 Approach (Variation):
"Digital platforms fundamentally reconfigure pedagogical delivery. These technologies
facilitate personalized learning pathways. Computational systems enable real-time
assessment mechanisms. Such innovations cultivate critical competencies essential
for contemporary employment contexts."
Vocabulary: platforms, technologies, systems, innovations
+ Synonyms: pedagogical delivery, learning pathways, real-time assessment, critical competencies
Result: Sophisticated vocabulary; Band floor = 7.5
How to Fix:
Band 6 Conclusions (Weak):
"In conclusion, I think technology is important for education. Technology helps
students, and education is necessary. My opinion is that technology should be used
more in schools."
Issues: Repetition, vague, no synthesis, personal pronoun, doesn't solidify argument
Band 8 Conclusions (Strong):
"While legitimate concerns persist regarding technology's potential to undermine
face-to-face interaction and critical thinking development, the pedagogical
advantages—particularly personalized learning pathways and immediate feedback
mechanisms—substantially outweigh these limitations. Future educational institutions
will likely prioritize technologically enhanced learning as foundational infrastructure,
provided implementation maintains pedagogical intentionality and human-centered
principles."
Elements:
- Acknowledges complexity (not simplistic)
- Reinstates thesis in new language
- Summarizes key supporting arguments
- Provides forward-looking perspective
- Maintains academic tone
"I disagree with this opinion. Technology has been very important for people to
communicate with each other. Many people use social media, email and phone calls
to contact friends and family. Technology is good for relationships.
First, technology helps people stay in contact with friends and family even if
they live far away. For example, my friend moved to another city and we use
Whatsapp to talk every day. Without technology, we would not be able to communicate
so easily. So technology helps relationships.
Second, people can meet new friends on the internet. Facebook and Twitter allow
people to connect and discuss topics. This is good for making relationships. Also,
people can share their life with others on social media. For instance, I post photos
on Instagram and people comment on them.
In conclusion, I believe technology is good for relationships. It helps people
communicate, make new friends, and stay in contact. In the future, technology will
be even more important for relationships."
BAND 6 Issues:
- Repetition: "technology", "good", "people", "relationships"
- Weak examples: "share their life" (too general)
- Personal anecdotes: "my friend", "I post" (less academic)
- Simple sentences: No complex clauses
- Thin explanation: "helps relationships" stated but not explained how/why
- Missing counterargument acknowledgment
- Run-on concluding thoughts
"I substantially disagree with the assertion that technology has been detrimental
to human relationships. While legitimate concerns regarding reduced face-to-face
interaction merit consideration, technological innovations have demonstrably enabled
relationship formation and maintenance previously impossible.
Technology has fundamentally expanded relational connectivity across geographic and
temporal barriers. Digital communication platforms enable individuals to maintain
meaningful connections despite physical separation. For instance, researchers at
Stanford University documented that individuals utilizing video-conferencing systems
experienced relationship satisfaction ratings comparable to in-person interactions,
suggesting that technological mediation does not inherently diminish relational quality.
Furthermore, digital platforms facilitate relationship initiation among individuals
with shared interests, enabling community formation around specialized topics that
geographic proximity alone could not facilitate.
However, excessive technology consumption may correlate with reduced face-to-face
interaction quality. Certain studies indicate that heavy social media usage demonstrates
weak correlations with reported loneliness metrics. Addressing this requires intentional
communication practices rather than rejecting technology itself.
Overall, technology represents a neutral tool whose relational impact depends upon
implementation practices. Rather than inherently damaging relationships, digital
platforms have expanded human capacity for connection, particularly benefiting
geographically dispersed individuals and facilitating community formation around shared
identities. Future social development will likely require integrating technological
connectivity with sustained face-to-face interaction investment."
BAND 7 Strengths:
- Academic language: "demonstrably enabled", "merit consideration"
- Research reference: Provides specific source attribution
- Concession: "While legitimate concerns..."
- Varied examples: Research + theoretical reasoning
- Complex sentence structures
BAND 7 Remaining Gaps:
- Could provide more specific research data
- Could strengthen explanation mechanisms
- Could develop counterargument more thoroughly
"I substantially disagree with the proposition that technology has been detrimental
to human relationships. Rather, technological innovations have fundamentally reconfigured
relational dynamics, expanding human capacity for connection while simultaneously
introducing new challenges requiring intentional navigation.
Technology has transcended geographic and temporal constraints that historically limited
relationship formation and maintenance. Digital communication platforms enable individuals
to cultivate meaningful connections despite physical separation. Research by Sprecher et
al. (2008) indicates that individuals utilizing synchronous video-conferencing systems
experienced relationship satisfaction ratings comparable to in-person interactions,
suggesting that technological mediation does not inherently compromise relational
authenticity. Furthermore, asynchronous digital platforms facilitate relationship
initiation among individuals with specialized interests, enabling community formation
around shared identities that geographic proximity alone could not facilitate—illustrating
technology's role in reducing social isolation among marginalized populations.
Legitimate concerns regarding excessive technology consumption warrant acknowledgment.
Certain longitudinal studies document weak correlations between heavy social media
consumption and self-reported relationship quality. However, this phenomenon reflects
implementation practices rather than technological determinism; intentional communication
boundaries mitigate these challenges without requiring technology rejection.
Rather than inherently damaging relationships, technology represents a contextually-dependent
tool enabling unprecedented connection while requiring disciplined usage practices. Digital
platforms have particularly benefited geographically dispersed individuals and facilitated
community formation among previously isolated populations. Future relational flourishing
will depend upon integrating technological connectivity with sustained face-to-face
interaction investment, suggesting synthesis rather than dichotomy between modes."
BAND 8 Distinctions:
- Sophisticated terminology: "transcended", "asynchronous", "relational authenticity", "technological determinism"
- Academic citation with author/date: (Sprecher et al., 2008)
- Nuanced concession: Acknowledges concerns but provides mechanism explanation
- Complex sentence structures with embedded clauses
- Sustained academic register throughout
- Strategic vocabulary precision: "contextually-dependent", "synthesis rather than dichotomy"
- Word choice shows sophistication: "mitigate" (not "fix"), "marginalized populations"
