If you have worked through the official dMAT interface material, you have seen its topics listed: Figure Sequences, Mathematical Equations, Latin Squares and Subject Module. The first three are recognisable task types. The fourth is a category rather than a task, and the material does not spell out in the same breath which subject module belongs to you. So candidates fill the gap themselves. An engineering graduate assumes there is an engineering paper somewhere that has not been found yet; someone from commerce or management goes looking for theirs. That search is often the first wasted week of a preparation, because on the route most Indian applicants are taking, the question has already been answered.
The exam is a Core Module plus one subject module
The structure is simpler than the naming makes it look. There are two modules, not four, and the certificate reflects that: it reports a score for the Core Module and a score for the relevant subject module, and the official description of the scoring says the total is those two values added together. Our note on reading your two module scores covers what that total can hide.
The other three entries on that list — figure sequences, mathematical equations and Latin squares — are Core subtests. As the syllabus overview sets out, they are bundled into a single block of roughly ninety minutes, with on-screen instructions between them. "Subject Module" is not a fourth Core subtest sitting quietly at the end of that list. It is the other half of the exam, and it is the half whose name changes depending on who is asking for your result.
On the APS India route, that module is the General Academic Module
This is the part worth reading slowly. The published description of the certificate lists what it reports: the Core Module and the relevant subject module — including the General Academic Module for the APS India route. Read against the interface list, that resolves the puzzle: where official material says "Subject Module", the module you sit on this route is the General Academic Module.
Two things follow, and the second is less obvious than the first.
The first is that there is no degree-specific paper to go and find. Your previous degree field does a great deal of work in this process, but it does that work earlier: it is part of what decides whether the requirement reaches your application at all, which am I affected? walks through. It does not then hand you a matching subject paper. Engineering, commerce and management applicants on this route are pointed at the same second module.
The second is that "General Academic" describes the module rather than standing in for something more specific. It is general in the sense that its material is not drawn from your field, and that is a design decision rather than an omission. As reading dMAT passages outside your field argues, a module that assumed the knowledge of one degree would end up measuring which degree you hold instead of how you reason.
The usual caution applies here with more force than normal. The dMAT serves more than one route, wording of this kind gets revised between cycles, and the official sources are the only place the current version lives. Confirm the module you are sitting against the official dMAT and APS India pages before you build a plan on it, and if what you read there differs from any summary, including this one, the official sources win. When sources disagree about dMAT eligibility is about exactly that habit.
Why the naming matters when you pick practice material
Getting this wrong costs time in two directions.
One is the search itself: weeks spent hunting for engineering or finance practice sets that were never part of this exam, and settling instead on material from some other test that happens to carry a reassuring label. Field-specific familiarity is not what this module asks for, so practice built around one field trains the wrong thing.
The other direction is quieter and more common. Candidates skip the official Subject Module material because it looks generic next to three named Core task types. They work carefully through figure sequences, equations and Latin squares, where progress is easy to see, and leave the fourth entry on the list for later. It is one of the two scores on the certificate. How to use the official dMAT preparation materials sets out how to work through all of it rather than only the parts that feel most like practice.
Once you know the second module is the General Academic Module, its preparation stops being vague. It is reasoning over unfamiliar academic material under time — following an argument, locating evidence, reading data carefully — and preparing for the General Academic Module covers that method in detail.
What it changes about your plan
Mostly it changes the arithmetic of where your hours go. If the total is the two module scores added together, then toward that total a point is a point, and the useful question is where your next hour is worth more of them rather than which module sounds more important. Splitting your time between the modules works that through properly.
It also gives you something to measure rather than estimate. A timed run that reports both halves separately will tell you which one sits further from where you need it, and the free dMAT practice test is enough for a first read. An impression of which module is your weaker one is worth much less than a result, and the two disagree more often than you would expect.
So the answer to the question in the title is short, and on this route it is the same answer for everybody: the Core Module and the General Academic Module. The reason it takes a page to say is that official material names the second one generically, and a generic name invites a search. Check it once against the official sources, write it down, and spend the hours you would have spent looking on the module you are actually sitting.
