A practical 8-week plan
Weeks 1–2 (foundation): read The Official Cambridge Guide cover to cover. Take notes on the four criteria. Write one Task 1 and one Task 2 — do not time them, just get used to the format. Submit to the checker.
Weeks 3–6 (practice): complete Cambridge IELTS 19 Tests 1 and 2. Write one Task 1 and one Task 2 timed (20 + 40 minutes) twice a week. Submit every essay. Track your criterion scores in a spreadsheet.
Weeks 7–8 (exam simulation): complete Cambridge IELTS 19 Tests 3 and 4 under full exam conditions (Reading + Listening + Writing in one sitting). Score yourself honestly. If your lowest criterion is still at 6.0, defer the exam by 2-4 weeks.
Frequently Asked Questions
What is the single best IELTS prep book in 2026?▾
The Cambridge IELTS 19 Official Practice Tests is the single most useful book overall. It contains four real past tests with authentic examiner comments. For strategy, pair it with The Official Cambridge Guide to IELTS. Two books are enough — adding more dilutes practice time.
Are online IELTS prep courses better than books?▾
Online courses are better for structure and accountability, but books are better for self-paced practice. The fastest path combines both: use a course for the first 2-3 weeks to learn the framework, then switch to self-practice with past tests and a free checker for daily feedback.
How long before my IELTS test should I start preparing?▾
8 to 12 weeks is the realistic window. Less than 6 weeks and you cannot move the band; more than 16 weeks and motivation drops. Plan 4 hours per week for the first 4 weeks (strategy + 1 essay per week), then 6 hours per week for the final 4–8 weeks (2 essays per week + listening/reading balance).
Do I need different books for Academic and General Training?▾
Yes, for the Writing task type. Academic Writing Task 1 describes a graph or diagram; General Training Task 1 is a letter. The Task 2 essay is structurally identical. Cambridge publishes separate Academic and General Training books; pick the one that matches the test you are taking.
