The dMAT is new, which means the market has not yet filled with material for it — and most of what is being sold under the name is for a different exam. That is manageable if you prepare the right things.
Start with the official materials, because they are the only official ones. g.a.s.t. publish preparation material, sample tasks, worked solutions and short videos showing exactly how each subtest behaves on screen — figure sequences, mathematical equations, Latin squares, and the subject module. They also say plainly that no further detail will be shown to you during the exam. Work through all of it. Knowing where the buttons are is worth marks on a timed digital test.
Then train the three habits, not the content. Every part of this test rewards the same three things, and you can practise them on anything:
- naming the rule before choosing — on sequences, on grids, on arguments
- eliminating on a proved contradiction rather than selecting on a feeling
- working from the tightest constraint first, which is what turns a hard item into a short one
Sudoku and logic grids train the third. Any reasoning-style verbal material trains the second. Figure-sequence practice from any source trains the first, because the dimensions that change are the same everywhere.
Practise at pace, in one sitting. Three and a half hours with a break is a stamina event, and stamina is the thing nobody practises. Two full-length sittings before the day are worth more than another fifty loose questions.
Do not chase a syllabus that does not exist. There is no chemistry to revise for the General Academic Module, and no formula sheet to memorise. If a course is selling you one, it is selling you a different exam.
Get the admin right, because it gates everything. Registration, payment, centre booking, technical support and the certificate are all g.a.s.t.; the APS certificate follows the dMAT result. Register early enough to get the centre you want, take your identity documents exactly as the candidate information sheet specifies, and check your anabin status before any of it.
