How to Attempt MCQs — Elimination Strategy for JEE/NEET
How to attempt MCQs in JEE, NEET and CUET: the elimination method, when guessing pays under negative marking, common traps and a three-pass time plan.
To attempt MCQs well: read the question fully, eliminate the options you know are wrong, answer the easy ones in a first pass, and guess only when elimination has improved your odds. JEE Main has 75 compulsory questions (60 MCQs and 15 numericals, −1 for a wrong answer on both) in 3 hours; NEET-UG has 180 compulsory questions in 3 hours. Here is the system.
The Elimination Method
- Read the question carefully — identify what is being asked
- Eliminate obviously wrong options first — ruling out one lifts your odds from 25% to 33%; ruling out two lifts them to 50%
- Look for extreme words (‘always’, ‘never’, ‘all’) — these are often, though not always, wrong
- Check dimensions/units — in Physics, wrong units instantly eliminate options
- Substitute values — plug in simple numbers (0, 1, −1) to test options quickly
When to Guess and When to Skip
| Exam | Marking | Should You Guess? |
|---|---|---|
| JEE Main | +4 correct, −1 wrong (MCQs and numericals) | MCQs: when you have ruled out at least one option. Numericals: only if you have worked it out |
| NEET-UG | +4 correct, −1 wrong | When you have ruled out at least one option |
| CUET UG | +5 correct, −1 wrong | When you have ruled out at least one option |
| Board MCQ (no negative) | +1, no penalty | Always attempt — never leave blank |
Common MCQ Traps
- ‘All of the above’ — if you know 2 are correct, this is likely the answer
- ‘None of the above’ — check your calculation twice before selecting this
- Similar-looking options — examiners often build a trap next to the right answer, so compare them carefully
- Negative signs in Physics — check the sign convention carefully
- Approximate values in Chemistry — use atomic masses given in the paper, not memorised ones
Time Strategy for MCQ Exams
- First pass (90 min): Attempt all questions you can solve in under 2 minutes
- Second pass (60 min): Attempt questions requiring 3–5 minutes of working
- Third pass (30 min): Review marked questions, check for errors
- Change an answer when you find a clear reason — studies of answer changing find more changes go from wrong to right than the reverse. Just don't change on a vague feeling

Is guessing worth it in JEE/NEET?
Do the maths: with four options and +4/−1 marking, a blind guess averages +0.25 marks, but it is a gamble. Knock out one wrong option and a guess averages about +0.67; knock out two and it averages +1.5. So eliminate first, and guess when you have ruled out at least one option.
How to improve MCQ speed?
Practice with a timer. Solve 30 MCQs in 40 minutes daily. Focus on pattern recognition — after solving 500+ MCQs, you will recognise question types instantly. Use previous year papers for practice.
Should I mark the OMR as I go or at the end?
In pen-and-paper exams, mark answers on the question paper first and transfer them to the OMR in batches of 10–15 questions — never all at the end. JEE Main is computer-based, and NEET-UG is moving to computer-based testing from 2027, so practise on screen for those.
