Exam-Day Strategy for MCQ Tests: Time Management, the Two-Pass Method and Negative Marking

Months of preparation can be undone in two hours by poor time management or panic. The good news is that exam-day performance is a skill you can plan and practise. This guide covers the day before, the morning of the exam, the first five minutes in the hall and a proven method for moving through the paper.

The day before the exam

The morning of the exam

  1. Eat a light meal you are used to.
  2. Leave early enough to reach before the reporting time, not the gate-closing time. Security checks and biometric registration take time.
  3. Avoid discussing "important questions" with other candidates at the gate; it only adds stress.
  4. Take a few slow breaths before entering the lab or hall.

The first five minutes at the computer

Most computer-based tests show instructions and a demo screen before the timer starts. Use this time to:

The two-pass method

The biggest time trap in an MCQ exam is getting stuck on one hard question. The two-pass method avoids it.

Pass 1 — the sure-shots (about 70% of the time)

Go through the paper in your chosen section order. For every question:

Set a soft time limit per question — for example, around 45 seconds for GK and language, and around 75–90 seconds for maths and reasoning.

Pass 2 — the marked questions (about 25% of the time)

Return to the marked questions, starting with the ones you think you can solve. Now you are working with whatever time is left, without the worry that easy marks are still waiting at the end of the paper.

Final check (about 5% of the time)

Use the last few minutes to make sure every answered question is saved and that you have not accidentally left an answer you meant to give.

Sample time plan for a 120-minute, 100-question paper

Phase Time Target
Pass 1: GK and languages 0–35 min 50–55 questions answered
Pass 1: reasoning 35–60 min Most reasoning questions done
Pass 1: quant 60–90 min Short arithmetic done; long items marked
Pass 2 90–112 min Marked questions
Final check 112–120 min Review palette and save

Practise this plan in at least five mocks before the exam so that the timings feel natural.

Negative marking: when to guess

If a wrong answer costs a fraction of a mark, random guessing becomes risky. For a four-option question with +1 for correct and −0.25 for wrong:

Situation Chance of being right Expected marks per guess
Pure guess 25% about +0.06
One option eliminated 33% about +0.17
Two options eliminated 50% about +0.38

So: guess only when you can eliminate at least two options, and be even stricter if the penalty is larger (for example −0.33 or −0.5). If there is no negative marking, answer every question.

Handling panic

After the exam

Note down the questions you remember, especially doubtful ones, while they are fresh. When the provisional answer key is released, compare carefully and raise objections, with evidence, within the deadline.

Practice questions

  1. Q1. A paper has 100 questions in 120 minutes. If you reserve 20 minutes for review, how many seconds are left per question?

    • (a) 50
    • (b) 60
    • (c) 72
    • (d) 80
    Show answer

    Answer: (b) 60 — 100 minutes = 6,000 seconds ÷ 100 = 60 seconds per question.

  2. Q2. With −0.25 for a wrong answer, which situation justifies a guess?

    • (a) You have no idea at all
    • (b) You can eliminate two of the four options
    • (c) The question is the last in the section
    • (d) You have time left
    Show answer

    Answer: (b) You can eliminate two of the four options — With two options eliminated, the expected gain per guess is clearly positive (about +0.38).

  3. Q3. A candidate answers 72 questions: 60 right, 12 wrong, with −0.25 per wrong answer. What is the score?

    • (a) 57
    • (b) 60
    • (c) 63
    • (d) 54
    Show answer

    Answer: (a) 57 — 60 − 12 × 0.25 = 60 − 3 = 57.

  4. Q4. In the two-pass method, a long but solvable question in pass 1 should be:

    • (a) Solved immediately whatever the time
    • (b) Marked for review and attempted in pass 2
    • (c) Answered with a guess
    • (d) Ignored completely
    Show answer

    Answer: (b) Marked for review and attempted in pass 2 — Marking it keeps time free for quicker questions first.

  5. Q5. If there is no negative marking, the best strategy is to:

    • (a) Leave doubtful questions blank
    • (b) Answer every question
    • (c) Answer only sure questions
    • (d) Answer only half the paper
    Show answer

    Answer: (b) Answer every question — Without negative marking, a guess can only add marks.

Frequently asked questions

Should I start with my strongest section?

Usually yes. Starting with a strong, fast section builds confidence and banks marks early. Test the order in mocks first.

What should I carry to a computer-based test?

Only what the admit card allows: normally the admit card, a valid original photo ID and sometimes photographs. Electronic devices are prohibited.

What if I run out of time?

Do not panic-guess the remaining questions if negative marking applies. Use the last minute to make sure your answered questions are saved.
