GATE 2027 Exam Pattern and Marking Scheme Explained

This page applies to every GATE 2027 paper. The pattern, the question types and the marking rules are the same whether you are appearing for Statistics, Data Science or Mathematics.

A GATE paper carries 100 marks across 65 questions in 3 hours. General Aptitude contributes 10 questions worth 15 marks and the subject contributes 55 questions worth 85 marks. This structure is common to Statistics (ST), Data Science (DA), Mathematics (MA) and most other GATE papers. Questions appear in three formats: MCQ, MSQ and NAT. Negative marking applies only to MCQs, at one third of a mark for a 1 mark question and two thirds of a mark for a 2 mark question. MSQ and NAT questions carry no negative marking and no partial marking.

Paper Structure

Section	Questions	Marks
General Aptitude	10	15
Subject, for example Statistics	55	85
Total	65	100

Duration is 3 hours. The paper is conducted as a Computer Based Test in English, and an on screen virtual calculator is provided. Physical calculators are not permitted.

The subject section contributes more than five times the marks of General Aptitude. That said, 15 marks is 15 percent of the paper for a section that needs roughly three weeks of total preparation across five months. Students who skip General Aptitude entirely are giving away the cheapest marks available to them.

The Three Question Types

Type	Full Name	How It Works	Negative Marking
MCQ	Multiple Choice Question	Four options, exactly one is correct	Yes
MSQ	Multiple Select Question	Four options, one or more may be correct	No
NAT	Numerical Answer Type	No options, you type the number	No

The exact split between MCQ, MSQ and NAT changes from year to year. GATE does not announce it in advance and it is not fixed. Questions carry either 1 mark or 2 marks.

Marking Scheme

MCQ

Question Value	Correct Answer	Incorrect Answer
1 mark	+1	−1/3
2 marks	+2	−2/3

MSQ

• No negative marking
• No partial marking
• You must select every correct option and no incorrect option to earn the marks

NAT

• No negative marking
• The answer is typed using the on screen keypad
• Signs, decimal placement and rounding must be checked before you move on

How to Attempt Each Type

This is where most of the avoidable marks are lost, so it is worth being precise.

MCQ Strategy

Negative marking here is real and it compounds. Three wrong 2 mark MCQs cost you two full marks, which is an entire question thrown away.

• Read every option before selecting. GATE frequently places a plausible near answer immediately before the correct one.
• Use elimination only when you can justify why an option is wrong, not when it merely feels unlikely.
• If you can eliminate two of four options confidently, a guess is mathematically reasonable. If you cannot eliminate anything, leave it.
• Never guess blindly to fill the screen. The paper does not reward attempted questions, it rewards correct ones.

MSQ Strategy

This is the format students handle worst, because the absence of negative marking creates false confidence.

• There is no partial credit. Getting three of four options right earns you nothing.
• Evaluate each option independently, as a separate true or false question. Do not look for a pattern across options.
• An MSQ where you are certain about two options and unsure about a third is not a safe attempt. It is a coin toss for the whole mark.
• Because there is no penalty, attempt it if you have any reasonable basis. Just do not spend three minutes on a guess.

NAT Strategy

No negative marking makes NAT the most attemptable format, and also the format where careless errors cost the most.

• Check the sign. A negative answer entered as positive earns zero.
• Check the decimal places. If the question asks for an answer correct to two decimal places, give exactly that.
• Check the unit implied by the question before converting anything.
• Do the final calculation on the virtual calculator rather than mentally, because arithmetic slips under time pressure are common.
• Write the answer on your rough sheet before typing it, then verify what you typed matches.

The Virtual Calculator

GATE provides an on screen scientific calculator and disables the physical keyboard for numerical entry. Two things follow from this.

First, it is slower than you expect. Every click takes time. A calculation that takes fifteen seconds on a physical calculator can take forty five seconds on the virtual one.

Second, it needs practice. Students who first meet the virtual calculator on exam day lose several minutes across the paper simply fumbling with it. Attempt at least ten full length mocks on an interface that replicates it.

A Realistic Time Plan

Three hours for 65 questions works out to roughly 2 minutes and 45 seconds per question. That average is misleading, because a 1 mark aptitude question and a 2 mark estimation question are not comparable.

A workable structure:

Phase	Approximate Time	What You Do
First scan	10 minutes	Go through the whole paper, marking questions as easy, doable or leave
Easy questions	50 minutes	Secure every direct mark, including General Aptitude
Moderate questions	80 minutes	The main solving phase, calculation heavy questions
Difficult questions	25 minutes	Attempt only what remains worth attempting
Final review	15 minutes	Verify every NAT entry and revisit marked questions

The single rule that protects your score: never let one difficult question consume the time that three easier questions needed. If a question has taken four minutes and you are not close, mark it and move. You can return. You cannot get the four minutes back.

You Cannot Practise Exam Pattern on Paper

Reading about MCQ, MSQ and NAT is not the same as handling them on a running clock with a virtual calculator. Chakravyuh Mock puts all 53 tests and all eight ST previous year papers on the real exam interface, with General Aptitude in every full length mock and All India Rank in every test.

Common Pattern Mistakes

1. Treating MSQs like MCQs. Selecting one option out of habit when more than one is correct earns zero.
2. Guessing MCQs to raise the attempt count. A higher attempt count with a lower score is a worse result.
3. Leaving NAT questions blank because the answer looks odd. There is no penalty. If you have a number, enter it.
4. Skipping General Aptitude to save time for Statistics. Fifteen marks of comparatively easy questions is not the section to sacrifice.
5. Meeting the virtual calculator for the first time on exam day.
6. No review pass. NAT entry errors are the most recoverable mistakes in the paper, and only a review pass catches them.
