Which dMAT subtest do Indian engineering students typically underestimate during preparation?

It is Latin Squares, not Mathematical Equations, that Indian engineering students most often underestimate. Your algebra speed from JEE and GATE preparation gives you false confidence, while grid-based elimination logic quietly needs far more practice than you expect.

Why Latin Squares catch students out

Indian engineering students tend to over-trust their algebra speed from JEE and GATE-style preparation and under-practice grid-based elimination logic. Latin Squares-style puzzles rarely show up in Indian engineering coursework the way they do in aptitude tests like TestAS or GMAT.

Do not neglect the Subject Module

Students also generally over-prepare for the Core Module's logic puzzles overall because they feel more approachable to revise for, and under-prepare for the Subject Module because there is no obvious textbook to open.

In practice, the Subject Module carries equal weight in your combined score and is twice as long as any single Core subtest, so split your practice time accordingly rather than defaulting to Core Module drills.

My Advice

Deliberately schedule more Latin Squares practice than feels necessary, especially if your instinct is to spend more time on Mathematical Equations because algebra feels familiar. Splitting your practice roughly in proportion to actual exam weight, rather than to what feels comfortable, is what separates a balanced score from a lopsided one.
