GATE uses three question types, and their marking rules are not the same. Getting this right shapes how you approach every question. This guide uses the GATE 2027 pattern published by IIT Madras, the organising institute. GATE 2027 is scheduled for 6, 7, 13, 14, 20 and 21 February 2027, with results on 19 March 2027; IIT Madras says all dates are liable to change.
What is the GATE exam pattern?
| Item | GATE 2027 |
|---|---|
| Duration | 3 hours |
| Questions | 65: 10 General Aptitude + 55 subject |
| Total marks | 100 |
| Question types | MCQ, MSQ and NAT |
| Mode | Computer-based, in English |
| Calculator | Virtual on-screen scientific calculator only |
General Aptitude carries 15 marks in every paper. How the other 85 marks are split depends on your paper. The full breakdown is on our GATE exam pattern page.
What are MCQ, MSQ and NAT questions?
- MCQ (Multiple Choice Question): choose one correct option.
- MSQ (Multiple Select Question): one or more of the options can be correct, and you select all that apply.
- NAT (Numerical Answer Type): no options; you enter a number.
Each type comes in 1-mark and 2-mark versions.
How is each question type marked?
| Type | Marks if correct | Wrong answer | Partial credit |
|---|---|---|---|
| MCQ, 1 mark | +1 | −1/3 | Not applicable |
| MCQ, 2 marks | +2 | −2/3 | Not applicable |
| MSQ | 1 or 2 | No negative marking | None |
| NAT | 1 or 2 | No negative marking | Not applicable |
The two rules to remember:
- Only MCQs can cost you marks.
- MSQs are all or nothing. No negative, but no partial credit either.
When is it worth guessing an MCQ in GATE?
Use expected value: the average result of a decision if you made it many times.
- Expected value = (chance right × marks) − (chance wrong × penalty)
The arithmetic below assumes four options with one correct answer. For a 1-mark MCQ, the penalty is 1/3:
| Situation | Chance right | Expected value |
|---|---|---|
| Blind guess | 25% | (0.25 × 1) − (0.75 × 1/3) = 0 |
| One option eliminated | about 33% | (1/3 × 1) − (2/3 × 1/3) = about +0.11 |
| Two options eliminated | 50% | (0.5 × 1) − (0.5 × 1/3) = about +0.33 |
For a 2-mark MCQ, every number doubles: a blind guess is still 0, one option eliminated gives about +0.22, and two eliminated gives about +0.67.
The pattern is neat. The penalty is set so that a blind guess on a four-option MCQ breaks exactly even on average. That means:
- Blind guessing gains nothing on average and adds risk. Skip it.
- Every option you can genuinely rule out tips the balance in your favour.
- The break-even point is a 1 in 4 chance of being right.
This is stricter than JEE Main or NEET, where the break-even point is 1 in 5. For comparison, see when a guess is worth it in JEE Main.
What counts as “ruling out” an option?
Only an option you can reject for a clear reason: wrong units, fails a limiting case, contradicts a definition, gives an impossible value. “Looks unlikely” is not elimination. If you wrongly eliminate the correct answer, a guess you thought was 50-50 becomes a sure loss.
How should you approach MSQs?
MSQs carry no penalty, so an answer can never lose you marks. That changes the decision:
- Always enter an answer if you have one, even a tentative one, as long as the time is available.
- Because there is no partial credit, think about each option independently. You need the exact set of correct options. One missed option, or one extra, and you get zero for that question.
- Do not assume a fixed number of correct options. An MSQ can have one correct option or several.
The cost of an MSQ is time, not marks. Spend your effort where you have a real chance of getting the full set right.
How should you approach NATs?
NATs also carry no negative marking. If you have worked out an answer, enter it. Even an answer you are unsure about can only gain marks.
Practical points:
- Use the virtual calculator well. It is the only calculator allowed, so practise with an on-screen scientific calculator before the exam.
- Read what the question asks for: units, the form of the answer and how many decimal places.
- A wrong NAT costs nothing in marks, but it does cost the time you spent. Do not sink ten minutes into a NAT you have little chance of finishing.
What does this mean for your strategy?
Put together, the marking rules suggest a clear order of priorities:
- Questions you can solve with confidence, of any type. Bank these first.
- NATs and MSQs where you have partial progress. There is no penalty for trying.
- MCQs where you can rule out at least one option. The expected value is positive.
- Blind MCQ guesses: skip. On a four-option MCQ, they break even on average and only add risk.
General Aptitude carries 15 of the 100 marks in every paper, and its syllabus (verbal, quantitative, analytical and spatial aptitude) is the same whichever paper you take, so it is worth preparing well.
How do GATE qualifying marks work?
Each paper has its own qualifying mark out of 100. In the GATE 2026 cutoff table, the OBC-NCL/EWS cutoff is 90% of the General cutoff for each paper. According to the GATE 2027 FAQs, a scorecard is issued only to candidates who reach at least the SC/ST/PwD qualifying mark for their paper. The GATE 2026 cutoffs by paper are on our GATE cutoff page. A GATE score is valid for three years from the date results are announced.
How should you practise?
- Take full papers under real conditions with an on-screen calculator.
- After each one, tally marks lost to wrong MCQs separately from marks not earned on MSQs and NATs. They need different fixes.
- Track how often your “eliminated” MCQ guesses are right. If they are not clearly better than chance, be stricter about elimination.
