In JEE Main and NEET, a correct answer earns 4 marks and a wrong answer costs 1 (check the latest information bulletin for the current scheme). That one rule decides a surprising number of ranks. Students who guess too much lose marks quietly; students who are too cautious leave marks they could have earned.
The basic arithmetic
With four options, a blind guess has a 1 in 4 chance of being right. On average that earns 4 × ¼ − 1 × ¾ = +0.25 marks per question. That sounds positive, but blind guesses are rarely truly random: question setters design wrong options that look right, so a student's "guess" is often pulled towards a trap. And every guess adds uncertainty to your score.
The picture changes completely when you can eliminate options:
- One option eliminated (1 in 3 chance): 4 × ⅓ − 1 × ⅔ ≈ +0.67 marks on average.
- Two options eliminated (1 in 2 chance): 4 × ½ − 1 × ½ = +1.5 marks on average.
So the practical rule many teachers give is: if you can genuinely eliminate two options, attempt; if you cannot eliminate any, skip.
Accuracy beats attempts
Compare two students in a 180-question paper:
- Student A attempts 160 questions with 75% accuracy: 120 right, 40 wrong, so 480 − 40 = 440.
- Student B attempts 145 with 90% accuracy: about 130 right, 15 wrong, so 520 − 15 = 505.
Student B attempted fewer questions and scored 65 marks more. High accuracy almost always beats high attempts.
Find your own numbers from mocks
After every mock, record:
- attempts and accuracy for each subject,
- marks lost to wrong answers,
- how your "sure", "50-50" and "guess" answers actually turned out.
Mark each attempt during the test with a small symbol: ✓ for sure, ~ for 50-50, ? for guess. After a few mocks you will know, for example, that your 50-50 answers are right 60% of the time in Chemistry but only 35% in Physics. That tells you exactly where to attempt and where to skip.
Numerical questions
JEE Main numerical-value questions have no options to eliminate, and wrong answers can carry negative marks. Attempt them when you have worked them through properly. Do not enter a guessed number.
Strategy in the exam hall
- First pass: attempt every question you are sure of. Skip anything that needs more than about two minutes of thought.
- Second pass: return to the marked questions and attempt those where you can eliminate options.
- Final minutes: check bubbles or responses rather than making new blind guesses.
Common mistakes
- Changing a correct answer at the last minute without a clear reason.
- Setting a target number of attempts ("I must attempt 170") and forcing guesses to reach it.
- Panicking after one hard section and guessing through the rest.
Every HAwk ACademe mock test comes with an analysis of attempts, accuracy and negative marks, so students can find the strategy that works for them. See our JEE and NEET programs, and read what a good mock test review looks like.
