Start with a diagnostic mock
Take a full mock 10–12 weeks before your earliest possible test date. The band breakdown shows your gap to the score you need — that gap determines prep length.
Typical preparation timelines
Band 5 → 6.5 often needs 8–12 weeks of focused study. Band 6.5 → 7 may need 4–8 weeks if one module lags. Students starting below band 5 should plan 3–6 months.
Align with university and visa deadlines
Book the official test at least 6 weeks before your application deadline — IELTS results take 3–5 days (CBT) but slots fill fast. Leave one retake buffer if your programme allows.
Signs you're ready
Two consecutive full mocks at or above your target band — with no module more than 0.5 below requirement — suggest readiness. One good mock can be luck; two is a trend.
