GATE 2027 Marking Scheme: Negative Marking, NAT Questions and Section-Wise Weightage

GATE 2027 carries 100 marks across 65 questions in a 3-hour paper, with negative marking of -1/3 for 1-mark MCQs and -2/3 for 2-mark MCQs — NAT and MSQ questions carry no penalty for incorrect answers.

GATE 2027 is expected to be conducted by IIT Madras as the organising institute. The marking scheme for GATE 2027 is expected to follow the same structure as previous years, as the pattern has remained consistent across cycles. Understanding how marks are awarded and deducted helps you plan your attempt strategy — especially around when to skip MCQs and when to freely attempt NAT questions.

• Total marks: 100; total questions: 65; exam duration: 3 hours
• Three question types: MCQ (negative marking applies), MSQ (no negative marking), and NAT (no negative marking)
• General Aptitude section: 15 marks — 10 questions (5 of 1 mark and 5 of 2 marks)
• Subject-specific section: 85 marks across 55 questions
• Negative marking for 1-mark MCQs: -1/3 (approx. -0.33); for 2-mark MCQs: -2/3 (approx. -0.67)

GATE 2027 Marking Scheme Overview

GATE 2027 is a computer-based test with 65 questions carrying a total of 100 marks. The paper has two sections: General Aptitude (15 marks) and the subject-specific section (85 marks). Three question types appear — MCQ, MSQ, and NAT — each with different marking rules. The complete expected marking scheme for GATE 2027 is given in the table below.

Negative Marking Rules for MCQs in GATE 2027

MCQs in GATE 2027 have four options with exactly one correct answer. Negative marking applies only to MCQs — a wrong answer to a 1-mark MCQ deducts 0.33 marks, and a wrong answer to a 2-mark MCQ deducts 0.67 marks. Leaving a question unattempted carries no penalty. This rule has been consistent across GATE exams for several years and is expected to continue in GATE 2027.

A key implication: three wrong 1-mark MCQs cancel out one correct 1-mark MCQ. For 2-mark MCQs, three wrong answers cost you approximately 2 marks. Blind guessing on MCQs is statistically unfavourable.

NAT Questions: No Negative Marking in GATE 2027

NAT stands for Numerical Answer Type. NAT questions have no options — you enter a number directly using an on-screen virtual keypad. Because there is nothing to guess from a list, NAT questions carry zero negative marking in GATE 2027. A wrong numerical entry does not deduct any marks.

Key facts about NAT questions in GATE 2027:

• Answer entered as an integer or decimal via virtual keyboard — no clickable options
• No negative marking for wrong numerical entries
• NAT questions can be 1-mark or 2-mark
• For decimal answers, GATE specifies an acceptable range — any value within that range is accepted as correct
• A physical calculator is not allowed; an on-screen virtual calculator is provided during the exam
• Always attempt NAT questions — an incorrect entry costs nothing, so even a reasoned estimate is worth submitting

MSQ Questions and Marking Rules in GATE 2027

MSQ stands for Multiple Select Questions. These have four options and one or more options may be correct. You earn full marks only when you select all correct options and no incorrect ones — there is no partial marking for MSQs in GATE. Importantly, MSQ questions carry no negative marking, so an incorrect or incomplete selection scores zero but does not deduct marks.

MSQs are typically the trickiest question type because partial credit is not awarded. Attempt MSQs only when you are confident about identifying all correct options — though an incorrect attempt is not penalised, time spent on uncertain MSQs is better used elsewhere.

Section-Wise Weightage in GATE 2027

GATE 2027 has two main sections: General Aptitude (15 marks) and the subject-specific paper (85 marks). For most engineering papers, the subject section includes Engineering Mathematics, typically worth around 13 marks, with the remaining 72 marks from the core discipline. The weightage below is based on the standard GATE paper structure from previous years and is expected to continue in GATE 2027.

The exact split between Engineering Mathematics and core subject questions can vary slightly by paper code. For non-engineering papers (Humanities, Architecture, Life Sciences), the internal distribution may differ from the table above. Always refer to the official GATE 2027 information brochure for paper-specific details once released.

How to Avoid Negative Marking in GATE 2027

Poor MCQ guessing is one of the most common ways students lose marks in GATE. These strategies help you protect your score:

• Prioritise NAT and MSQ questions you can solve — no negative marking means zero risk on these types.
• Skip MCQs you cannot reason through — an unattempted MCQ scores 0, not a deduction. Skipping is always safer than blind guessing.
• Use elimination for MCQs — if you can confidently rule out two options, your probability of scoring positive improves significantly. Attempt if only two options remain.
• Avoid random guessing on MCQs — on 1-mark MCQs, three wrong answers cancel one correct answer. The expected value of a random guess is negative.
• Invest time in 2-mark questions you know well — the penalty is only 0.67 marks but the reward is 2 marks, giving a strong risk-reward ratio when you are confident.
• Flag and revisit uncertain MCQs — use the review feature to mark questions and return to them only if you can narrow down the choices further before time ends.
