Ask most candidates where they lose marks and they will point to the hardest questions. Look at a reviewed mock test, though, and a different picture usually emerges: a meaningful share of lost points come from questions the candidate could easily solve but got wrong through a slip — misreading the prompt, mis-transcribing a number, or filling in the wrong answer box. These are the cheapest marks to recover because the skill is already there; only the accuracy is missing. This article sets out practical habits for working carefully under time pressure so you keep the points you have earned.

Read the question as carefully as you solve it
Most careless errors are born at the start, in the reading, not at the end, in the working. A question asks which figure comes next and you find the one that came before; it asks for the value that does not fit and you pick one that does. The method was sound; the target was wrong. Slowing down for the two or three seconds it takes to register exactly what is being asked is one of the highest-return habits on the whole test.
Train yourself to notice the small words that flip a question: not, except, always, least, next, before. On a computer-based test you cannot underline them, but you can pause deliberately on them and hold the exact task in mind before you start working. The goal is to answer the question in front of you rather than the one you assumed it was — the same discipline that underpins careful reading comprehension.
Build a light checking rhythm
Perfect accuracy is not the aim — you do not have time to double-check everything, and trying to would cost you more marks than it saves. What works is a light checking rhythm: a quick, specific confirmation at the moment you commit to an answer. Before you move on, glance back at the question stem and confirm your answer actually addresses what was asked. This single beat catches a large share of slips without meaningfully slowing you down.
Pick checks that are cheap and targeted rather than a full re-solve. For a calculation, does the answer's size and sign look sensible? For a pattern, does your chosen rule hold for every visible step, not just the first? For a selected option, is it the one you actually meant to choose? These are the same confirmations that make our method checklists reliable — for instance, verifying a rule across all terms in number sequences — applied as a quick habit rather than a separate stage.
If your exam interface lets you flag items to revisit, use it deliberately: flag anything you rushed or felt unsure about, and if time remains at the end, spend it re-checking those rather than re-reading everything.
Manage the conditions that cause slips
Careless errors are not random; they cluster where your attention is weakest. Two conditions reliably produce them: rushing and fatigue. When you feel yourself speeding up because the clock is shrinking, that is exactly when accuracy collapses and easy marks leak away. Steady pacing protects accuracy far better than a late sprint — a principle covered in our note on working calmly under time pressure. A calm, consistent rhythm beats bursts of panic almost every time.
Fatigue is the other culprit, and it hits hardest in the back half of the exam. The tired brain skims, and skimming is where slips live. Building the concentration to stay accurate late is a preparation task in itself — the subject of building study stamina — but on the day it also helps to use any scheduled break to reset, and to consciously slow your reading when you notice your focus dipping.
Learn your own error signature
The most useful long-term fix is to find out which careless mistakes are yours. Everyone has a signature: some people consistently misread negatives, others transpose digits, others rush the final section. Keeping an error log that separates genuine knowledge gaps from pure slips will reveal your pattern quickly. Once you know it, you can watch for it specifically — a targeted guard is far more effective than a vague resolution to "be careful". Reviewing practice tests the way we describe in reviewing a mock test properly is where this signature becomes visible.
Keep the purpose in view
Avoiding careless mistakes is not about slowing to a crawl or checking everything twice. It is about reading the question as carefully as you solve it, adding one light confirmation before you commit, protecting your pace and focus, and knowing your own recurring slips well enough to guard against them. When you would like to practise accurate work under realistic conditions, sit original questions in the free dMAT diagnostic, then separate your misses into things you did not know and things you simply slipped on — and watch the second list shrink.
