The dMAT arrived in June 2026 with a September deadline, no past papers, no syllabus and a rule that forbids you from writing anything down. Most of the material that appeared in response was a PDF of puzzles.
A PDF cannot enforce a timer and cannot stop you picking up a pen — and those two constraints are the dMAT. Practising without them builds confidence in a skill the exam removes on test day. So we built the opposite: a browser-based test that behaves like the real thing, times you the way it does, and explains every answer afterwards.
Nobody outside g.a.s.t. has the official item bank, so we do not pretend to. Instead we built a generator that produces questions to the published task rules — the figure movement rules including x+1 acceleration and the two boundary behaviours, the 1-to-20 integer constraint on equations, the 5x5 Latin square constraint — at the same three difficulty tiers the official practice material uses.
Every generated item is machine-verified before it reaches you: each equation system is checked to have exactly one solution, each Latin square is checked to have exactly one valid completion, and each figure sequence is discarded if a candidate could not have deduced its rules from the matrices shown. Items with ambiguous answers are thrown away rather than shipped.
One practical consequence: because questions are generated rather than drawn from a small fixed bank, we can promise you will never see the same question twice.
