This is a checklist for getting your full ability onto the answer sheet on exam day. It is written for anyone about to sit an exam, and it covers 12 things to do, and not do, from the night before through the end of the test. The claim is simple: most points lost on exam day are lost to poor logistics, not to missing knowledge.

This isn't a pep talk; it's an observation. You drop a question on the day that you could solve the night before. You notice, with three minutes left, that your answer sheet has been shifted by one row. You misjudge the time and never reach questions you could have answered. None of these come from "I didn't know." They all come from "I didn't close the gap."

Your knowledge is fixed by the night before. The only thing you can do on the day is move that knowledge onto the answer sheet without spilling any of it. So this article says nothing about learning new material. It's only about not dropping the ability you already have.

Every item comes with one line on why it works. A checklist whose reasons you don't understand is the first thing to evaporate under exam-day nerves.

What should you do, and not do, the night before?

Leave new material alone, pack your bag completely, and fix one timeline from wake-up to arrival. That's the whole job for the night before.

  1. Don't cram new material. Material you see for the first time the night before adds almost nothing to your score. What it leaves behind is the anxiety of "I don't know that either." If you study at all, limit it to reviewing problems you've already solved or going over flashcards. → Why it works: New learning the night before fades in sleep before it consolidates. The anxiety, on the other hand, lingers into the morning and eats your focus. The gain is small and the loss is large, so skip the trade.

  2. Pack your bag the night before. Actually put things in it. Admission ticket, pens, a watch, ID, cash, transit card, a jacket. Don't lay them out on the desk to "check" them; physically put them in the bag. Anything you decide to "pack tomorrow" is the one thing you forget in the morning. → Why it works: Morning is when your judgment is at its lowest. Let the calm version of you, the night before, do the work for the rushed version of you in the morning. The point is moving the check to a calm hour.

  3. Decide one timeline, working backward from wake-up to arrival. For example, if the exam starts at 10:00 and the venue is an hour away, working backward gives you this:

  4. 9:30 — arrive (30 minutes early; margin for the restroom, getting seated, and settling your mind)
  5. 8:30 — leave home (1 hour of travel plus a buffer for delays)
  6. 7:30 — finish breakfast (your brain doesn't work right after eating; leave it an hour)
  7. 7:00 — wake up (the brain takes a while to come fully online, so a bit earlier wouldn't hurt)

→ Why it works: Work out the timing on the morning itself and nerves steal the spare capacity you'd need to calculate. Decide one timeline the night before and the morning becomes following the times you set. The total amount of judgment you have to make drops.

How should you handle your first ten minutes in the room?

Assume your mind will go blank. Start with a question you know you can solve, and if you can't see a path within 30 seconds to a minute, mark the question and move on.

Going blank from nerves isn't abnormal; it's the default. Plans break because they assume you won't go blank. Prepare, in advance, a procedure that runs even when you do.

  1. Build momentum with your first question. Hit a hard question right after the start and the panic of being stuck chains forward into later questions. So start with a question you know you can solve. You're under no obligation to answer in order. → Why it works: Solving one question restores the feeling that "I'm moving." That feeling physically lowers your nerves. Chase your first success by certainty, not by difficulty.

  2. For a question you can't do, mark it and move on. Grind on one stuck question and you lose both time and composure. If you don't see the path within 30 seconds to a minute of thinking, put a mark by the number (a triangle, say) and go to the next one. Come back later. → Why it works: A head worn down by a hard question goes on to drop the easy ones too. Skipping isn't running away; it's maximizing scoring efficiency. Rather than spend five minutes on a 3-point question, pick up three other questions.

  3. Use two kinds of marks. Mark "no idea at all (×)" differently from "probably this, but not confident (△)." If you have review time left, start with the △ ones. → Why it works: Review time tends to run short. Instead of reviewing everything, start with the high-upside △ items and you pick up the most points in the time you have.

How do you prevent marking errors and running out of time?

With a system, not willpower. Reserve your review time first, fix one marking method the night before, and confirm the answer row with your finger the moment you skip a question.

  1. Reserve your review time first. If the exam is 60 minutes, decide up front that you'll spend at most 50 minutes answering. The last 10 minutes are review-only. Work out a per-question cap with "(total time − review time) ÷ number of questions." → Why it works: Review time you'll "do if there's any left" is never left. It remains because you set it aside first. It's the same logic as saving from your paycheck before you spend.

  2. Decide the night before: mark as you solve each question, or mark them all at the end. Waver on the day and you'll start one method, break off, and create the breeding ground for a shift. Either method is fine. What matters is not hesitating over the method on the day. → Why it works: Most marking shifts happen the instant the method changes mid-exam. Fix one consistent method and the source of the shift disappears.

  3. If you skip a question, skip its answer row too. Confirm the match with your finger, not just your eyes. Each time, press your finger on the question number and on the row number of the answer sheet, and confirm they line up. → Why it works: One skipped question shifts every row after it by one. That's one of the biggest accidents on exam day. Physically confirming the row the moment you skip is the only reliable prevention.

What should you not do after the exam?

Don't burn yourself out grading. Put a finished subject out of your head, stay out of answer-checking during the break, and, if the exam runs over several days or subjects, feel free to hold off on self-grading until everything is over.

  1. When a subject is over, put it out of your head as finished. Dragging along the feeling of how it went lowers your focus on the next subject. The verdict of did-well or did-badly can wait until everything is done. → Why it works: The score of a finished subject can't move anymore. Thinking about what you can't move only steals time from the next subject, which you can.

  2. Don't check answers during the break. When people around you start saying "so what was the answer to that one," don't join in. Even if you realize a mistake, you can't take it back, and only the anxiety carries into the next subject. → Why it works: Self-grading during a break has zero upside and only downside. There's no situation where the information helps, so the rational move is to stay away.

  3. It's fine to hold off on self-grading until every session is over. For a multi-day, multi-subject exam, choosing not to look at any scoring until the end is a valid strategy. A bad mid-way result reliably drags down the exams that remain. → Why it works: Self-grading exists to "use next time." If exams remain, there's nowhere to apply it yet. Look at everything at once after it's over and you minimize the drain while maximizing the reflection.

What should you never do on exam day?

Pulling out just the "don't" side of the 12 items above gives you these five. The reason for each is in the item noted in parentheses.

  • Cram material you've never seen the night before (item 1)
  • Leave the packing check for the morning (item 2)
  • Keep grinding on a question you're stuck on (item 5)
  • Change your marking method partway through (item 8)
  • Join the answer-checking during the break (item 11)

Summary: the job on the day is moving your knowledge onto the sheet

Building knowledge is the job of the days before. The job on the day is to move that knowledge onto the answer sheet without losing a single point. It's plain work, but it swings several points right here.

This site has "passing" in its name. I hope the version of you who shows up on exam day gets to put out everything you've got.

FAQ

If I study the night before, what should I do?

Limit it to reviewing problems you've already solved or going over flashcards. Material you see for the first time adds almost nothing to your score, and the "I don't know that either" anxiety lingers into the morning.

How long should I think before skipping a question?

If you don't see a path within 30 seconds to a minute, put a mark by the number (a triangle, say) and move on. Come back later. A head worn down by a hard question goes on to drop the easy ones too.

How much review time should I reserve?

If the exam is 60 minutes, decide to spend at most 50 minutes answering and keep the last 10 for review only. Work out a per-question cap with "(total time − review time) ÷ number of questions." Review time you'll "do if there's any left" is never left.

Is it better to mark each answer as I go, or all at the end?

Either is fine. What matters is deciding on one method the night before and not hesitating on the day. Most marking shifts happen the instant the method changes mid-exam.

Is it okay to self-grade during the break?

No. Even if you spot a mistake, you can't take it back, and only the anxiety carries into the next subject. For a multi-day, multi-subject exam, it's fine to hold off on self-grading until every session is over.
