Most preparation happens on paper. You print a question set, spread it across the desk, circle the promising options, scribble a step in the margin and strike through what you have ruled out. Then you sit the dMAT, and none of that is available: the questions are on a monitor, the answers are selected with a mouse, and the working happens in your head. The distance between how you practise and how you will be tested is small enough to ignore for months and large enough to notice on the day. This article is about closing it.
Paper habits do not transfer
The syllabus describes an exam that is single-choice, in English and delivered on a computer, with each of the two modules running about ninety minutes. The Core module bundles its three subtests — Figure Sequences, Mathematical Equations and Latin Squares — with the instructions presented on screen. On rough paper the official position is straightforward: there is none, because those subtests are designed to be solved mentally.
That is worth reading as a description of a working method rather than merely a rule. On paper you offload constantly without noticing. A half-formed rule goes in the margin. Two eliminated options get a line through them. A partial sum sits at the top of the page while you work out the rest. Take the page away and every one of those small deposits has to be held somewhere else, which is why the capacity to hold them matters so much; our guide to training working memory covers that side of the problem in detail.
The mechanical losses are quieter but just as real. You cannot annotate a figure to mark what changed between two frames. You cannot fold the sheet to put a diagram beside its answer options. Your eyes travel between a figure at the top of the screen and the options below it, instead of taking in a whole page at a glance. None of this is difficult. It is simply unfamiliar, and unfamiliarity is expensive when the clock is running.
Move your everyday practice onto the computer
The fix is unglamorous: stop printing. Do your ordinary drills on a laptop or a desktop, at a desk, with a mouse if you have one.
A few details decide whether the switch is worth something or merely cosmetic.
- Use a real computer, not a phone. A phone reflows text, zooms on a pinch and shows you one element at a time. The exam will not adapt to you, and practising on a device that does teaches the wrong reflexes.
- Read at full size, one question at a time. Open the material full-screen and resist scrolling back and forth between several questions. Work the one in front of you and move on.
- Do not annotate the file. Highlighting a PDF or drawing on a tablet is the paper habit wearing a different coat. If the tool lets you mark the question, turn the tool off.
- Keep the desk as it will be. Notes, formula sheets and printed material are prohibited in the exam room, so practising with a reference sheet within reach quietly inflates your results.
- Use official on-screen material where it exists. Anything the official preparation resources provide in the exam's own format is worth more than a better-looking third-party set on paper.
This is the medium half of realistic practice. The timing, interruptions and routine around it are the other half, and our guide to simulating exam conditions covers those; the two work best together.
Hold your place without a pencil
Working on screen is mostly a problem of keeping track, and the answer is structure rather than effort. A fixed routine costs nothing to run and replaces the marks you would otherwise have made on the page.
Scan in a set order. For a matrix of figures, go along the rows and then down the columns, the same way every time, so that you are never re-scanning at random to check whether you missed something. Our framework for figure sequences sets out that kind of ordered pass; on screen it does double duty, because it also tells you where you have already been.
Use the cursor as a pointer. It is the one substitute for a finger on the page, and it is genuinely useful for holding a row, a cell or an option while your attention is elsewhere.
Name things instead of marking them. A rule you can say — "the inner shape rotates, the outer one stays" — survives in your head far better than a shape you are trying to picture. The same applies to elimination: rather than trying to remember everything you have ruled out, narrow to the options still standing and rehearse that short list. Our note on process of elimination describes the reasoning; on a screen, the discipline is to keep the surviving set small enough to carry.
Three hours in front of a monitor
Reading on a screen tends to be more tiring than reading on paper, and the exam is roughly three hours of testing plus a break. If your longest unbroken screen session in preparation has been twenty minutes, the second module will be your first experience of what the third hour feels like.
Build up to it deliberately, in the same way you would build any other kind of endurance — our guide to study stamina applies directly here. Sit properly, with the monitor an arm's length away and roughly at eye level, and take the break between modules as a chance to look at something further away than the screen for a few minutes.
One more thing worth rehearsing: the machine will not be yours. The screen size, the brightness and the chair are whatever the centre provides. Practising occasionally on a different computer, or at a setting slightly less comfortable than your favourite, makes that unremarkable rather than unsettling.
Make the format boring
The point of all this is not to add another task to your preparation. It is to remove a variable. When the screen is where you have always worked, test day presents you with questions rather than questions plus an unfamiliar way of meeting them.
Expect the first few sessions to feel slightly worse than paper did. That drop is the cost you were going to pay anyway, moved to a week where it does not count. When you want to see where you stand under both the format and the clock, take a timed run on the free dMAT practice test and treat the screen itself as part of what you are rehearsing.
