How many weeks should I spend preparing for the dMAT exam, and what should a study plan look like?

Most applicants need 4 to 6 weeks of focused preparation, extending to 8 weeks if you want a more gradual build. A structured six-week plan gives you enough time to learn the task types, build speed, and sit full timed mocks before exam day.

A reasonable six-week structure

Week 1, read the official g.a.s.t. preparatory material once, untimed. Week 2, attempt one full Core Module set under timed conditions to establish a baseline and identify your weakest subtest. Weeks 3 to 4, daily 20 to 30 minute drills rotating across Figure Sequences, Mathematical Equations, and Latin Squares, plus daily Subject Module passage practice.

Week 5, two full-length, timed mock exams under real conditions, with no calculator, no notes, and no pausing the timer. Week 6, re-drill only your weakest subtest and confirm your test-centre seat and ID documents.

Timing your plan to the exam date

If your test date is 26 September 2026, start Week 1 by mid-August so your six weeks land comfortably before the exam. Beginning later forces you to compress the most demanding timed practice into your final week.

My Advice

Start Week 1 by mid-August at the latest if you are targeting the 26 September exam date. Students who begin their six-week plan in early September end up compressing timed mock practice into their final, most stressful week, which is precisely the wrong time to be building new skills.
