I Tested 5 IELTS Strategies - Only One Actually Worked

Why I Decided to Test IELTS Strategies

After 20 years of invigilation, I started keeping informal records of the preparation approaches students described to me after their exams. Students who scored well and students who did not. What they had done differently. What they regretted. What they would change.

The patterns were striking enough that I started being more systematic about it. I grouped the strategies I heard most often into five categories and tracked outcomes over time.

I want to be honest with you: this is not a controlled scientific study. But it represents 20 years of direct observation across thousands of candidates. The patterns I am describing are genuine.

This is one of the most popular IELTS strategies I see. Students purchase vocabulary books, download word lists, watch YouTube channels dedicated to advanced English vocabulary, and spend hours each day memorising new words.

The outcomes: modest improvement in passive vocabulary recognition, which helps Reading and Listening. Very little improvement in Writing and Speaking, because knowing a word passively does not mean you can use it accurately under pressure.

The core problem with this strategy is transfer. Knowing that "ubiquitous" means "everywhere" does not mean you will use it correctly in a sentence under timed conditions without also knowing its typical collocations, the contexts it sounds natural in, and its register.

Verdict: helpful in small doses when combined with active production, but minimal impact as a standalone strategy.

Strategy 2: Grammar Rule Drilling

Students who identify Grammatical Range and Accuracy as a weakness often turn to grammar textbooks. They spend weeks drilling conditionals, passive voice, relative clauses, and reported speech.

The outcomes: understanding of grammar rules improves significantly. Accuracy in isolated grammar exercises improves. Accuracy in timed writing and speaking under pressure improves much less.

The gap between knowing a grammar rule and applying it correctly when you are also thinking about your argument, your vocabulary, your timing, and your next sentence is enormous. Grammar drilling alone does not close that gap.

Verdict: necessary for foundational understanding, but grammar rules must be practised in timed writing with feedback to produce meaningful band score improvement.

Strategy 3: Model Answer Copying

Many institutes recommend this. Students find Band 8 or Band 9 sample essays and copy them out by hand, sometimes repeatedly, to absorb the language patterns.

The outcomes: some improvement in awareness of essay structure and vocabulary in context. Minimal improvement in the student's own writing because copying is a passive activity with almost no transfer to independent production.

I also see a more harmful side effect. Students who spend too much time with model answers sometimes start attempting to reproduce them under exam conditions, which either fails (they cannot remember enough) or produces a suspiciously template-like response that lowers their Task Achievement score.

Verdict: study model answers analytically. Do not copy them. Use them to understand what Band 7+ writing looks like, then produce your own responses.

Strategy 4: Daily Mock Tests

This is the most time-intensive strategy I see students using, and one of the least efficient. Students do a full four-module mock test every single day, check their answers, note their score, and repeat tomorrow.

The outcomes: students become very comfortable with the test format and timing. Their scores stabilise, usually at their current level. Very few students show meaningful improvement over months of daily mock testing without structured review.

The problem is that doing a test and checking answers tells you what you got wrong. It does not tell you why. Without understanding the mechanism of your errors, you cannot change the behaviour that produced them.

Verdict: one well-reviewed mock test per week is far more valuable than seven superficially reviewed ones.

Strategy 5: Targeted Feedback Loops (The One That Works)

Here is the only IELTS strategy that consistently produces meaningful score improvement in my observation. It is not complicated. But it requires honesty about your weaknesses and discipline about acting on feedback.

The loop works like this. First, diagnose your weakest criterion in each module. Not your weakest module overall, but the specific criterion within each module that is pulling your score down. Second, practise that specific criterion deliberately and under timed conditions. Third, get criterion-level feedback on that practice. Fourth, identify the specific behaviour causing the error. Fifth, change that behaviour in your next attempt. Sixth, repeat.

The critical element that separates this from every other strategy is step three. Criterion-level feedback tells you which of the four IELTS dimensions is weak and why. Without that, you are guessing.

I have seen students use mockde.com for their writing feedback and discover that the criterion they thought was their weakness (usually Grammar) was actually fine, while the criterion they had been ignoring (usually Coherence) was the real problem. That single discovery typically produces more improvement than weeks of undirected practice.
