IELTS Academic full mock — how to run one that matters
Last updated: July 20, 2026
One accurate full-length mock is worth ten fragmented practice sessions — if you simulate the constraints that actually change your score.

- Total time
- ~2 hours 45 minutes across Listening, Reading and Writing (Speaking is separate)
- Listening
- ~30 minutes audio + 10 minutes transfer (paper) / no transfer (computer)
- Reading
- 60 minutes, three passages, 40 questions, no transfer time
- Writing
- 60 minutes total, Task 1 (150 words) + Task 2 (250 words)
- Speaking
- 11–14 minutes, live interview, often on a different day
What a realistic mock actually simulates
The point of a full-length mock is not to see 'a number'. It is to see whether the sequencing and fatigue of the real test change how you perform. The three sections that run back-to-back on test day — Listening, Reading and Writing — total roughly two and a half hours of concentrated language work, with only the shortest of breaks between them. Doing them separately, on separate days, does not measure the thing that goes wrong on test day: the drop in accuracy in the final 15 minutes of Writing Task 2.
- Sit through Listening + Reading + Writing back-to-back with only the official short pause between sections.
- Use paper or computer to match your booking. Paper Listening requires the 10-minute transfer window; simulate it.
- No phone, no dictionary, no re-listen, no rewind on Listening. One shot per audio track.
- Use exam-style answer sheets on paper mode; on computer mode use an equivalent clean interface.
- Book Speaking as a separate session — 11–14 minutes with an interlocutor, not with yourself.
What you should not simulate
Some candidates over-simulate and burn out. You do not need to travel to a physical test centre for a mock. You do not need to wear the same clothes. You do not need to eat the same breakfast. What matters is the cognitive load of the three sections in sequence, the fixed timing constraints, and the absence of the safety-net habits (rewind, re-read, notes-in-margin) you use in casual practice.
How to review a mock without over-reading it
One mock is one data point. It tells you your rough band range, where fatigue hit hardest, and which section is currently the ceiling — but a single score is not a prediction. Two mocks separated by two weeks of focused practice tell you much more, because the delta shows whether your training is working.
When reviewing, sort errors by cause, not just by section. A wrong Reading answer because you misread the question type is a different diagnostic from a wrong answer because you ran out of time. The first calls for question-type drilling; the second calls for pacing practice. Mixing the two hides the actual bottleneck.
How to slot mocks into a study plan
For most candidates preparing over 6–12 weeks, one mock in the first week (baseline) and one every 3–4 weeks after that is enough. More frequent full mocks stop showing new information because you have not had time to change any underlying skill between them. Between mocks, use section-by-section practice targeted at the bottleneck the last mock revealed.
In the final week before the real test, one calibration mock 5–7 days out is often useful — long enough before the exam to correct any pacing surprises, close enough that stamina carries over. Do not schedule a mock 24 hours before the test; you want a rested mind more than one last data point.
