How Long Should You Study for the GAMSAT?
6 min read · Updated 10 June 2026
There is no single right answer, but there is a sensible range. Most people give the GAMSAT two to four months of consistent preparation, and the right number for you depends on your background and how far your weakest section is from where it needs to be.
More useful than a fixed number of weeks is a plan built backwards from your test date.
The honest range
- Strong science background, good writer: two to three months can be enough.
- Rusty on science or weak on essays: three to four months, sometimes more.
- Less than a month: you can still lift specific weak spots and your timing, but do not expect to rebuild a section from scratch.
Plan backwards from the test date
Start from your sitting and work back. Reserve the final week for tapering, not cramming. Spend the early weeks building from familiarisation to question banks, the middle weeks drilling your weakest section, and the last few weeks on full timed practice and essays under exam conditions.
Hours per week beat total weeks
Consistency matters more than the calendar. A focused 8 to 12 hours a week, with real timed practice and feedback, beats sporadic cramming over a longer period.
Quality of feedback matters even more than hours. Practising without knowing what you got wrong just embeds your weaknesses.
Diagnose first, then plan
Before you decide how long you need, find out where you stand. Sit a short diagnostic across all three sections and mark an essay, then build your timeline around your actual gaps rather than a generic schedule.
