GATE Physics (PH): Paper, Cut-offs, Score & the 2027 Syllabus Change

GATE Physics is one of only six papers with no Engineering Mathematics section. Mathematical physics is Section 1 of the subject itself, not a bolt-on, so all 85 subject marks are physics.

Its qualifying bar has fallen in each of the last two cycles — 32 in GATE 2024, 26.8 in 2025, 25.5 in 2026 — while registrations have drifted down too. Section 3 explains what a falling bar actually means, because it is almost universally read backwards.

And for anyone preparing now, the biggest news is not in the data at all: the GATE 2027 Physics syllabus has been restructured from nine sections to eleven, with two areas that did not previously exist as sections of their own.

This article is about the Physics paper specifically: what is in it, what the qualifying mark and the GATE score actually measure, what the syllabus contains, and what IIT Madras has changed for GATE 2027.

If you have not sat GATE before, the general guide to the exam covers the rules common to all thirty papers — the marking scheme, eligibility and what a score is used for. This page assumes them.

Which year is this data from? The exam pattern, marking scheme, qualifying-mark formula, score formula, eligibility and fee are from the GATE 2026 Information Brochure published by IIT Guwahati. Candidate numbers and qualifying marks are from the official cut-off pages for GATE 2024, 2025 and 2026 — published by IISc Bengaluru, IIT Roorkee and IIT Guwahati respectively. The question-type breakdown is counted from the official GATE 2025 answer key.

GATE 2027 is organised by IIT Madras, and the syllabi have been revised. What changed for this paper is set out in section 5 below. This page is updated after each cycle rather than replaced, so the older figures stay here beside the new ones.

1. One exam, three destinations

Before the paper itself, the thing GATE is for. One score does three different jobs, and they do not treat it the same way.

What it is used for	How the score is treated
M.Tech, M.E., M.S. and M.Sc. at IITs, IISc, NITs and other centrally funded institutes	A three-year-old score is accepted. Many programmes carry a monthly stipend.
PhD admission at the same institutes	A three-year-old score is accepted, often directly after a bachelor’s degree.
Recruitment by public sector companies	Usually the current year’s score only.

That last row costs people a year. Your scorecard is valid for three years and institutes honour it; most PSU recruitment notices ask for the score from that year’s exam.

2. What is actually in the paper

Every GATE paper is the same shape: 65 questions, 100 marks, three hours, on a computer, in English. General Aptitude is 15 marks and is identical for all 30 papers; the remaining 85 are yours.

What differs between papers, and between years, is the mix of question types — and that mix decides how much of the paper you can attempt without risk. Here is GATE 2025 Physics, counted from the official answer key.

Section	Questions	Marks	Negative marking
General Aptitude — MCQ only	10	15	Yes, on every question
Subject — MCQ	24	35	Yes
Subject — MSQ	18	30	None
Subject — NAT	13	20	None
Total	65	100

Question type	What it is	Wrong answer costs
MCQ	Four options, exactly one correct	−1/3 on a 1-mark question, −2/3 on a 2-mark question
MSQ	One or more options correct	Nothing — but there is no partial credit either
NAT	Type the number; no options given	Nothing

50 of the 85 subject marks carried no penalty at all. In an MSQ or a NAT, a blank and a wrong answer score exactly the same — zero — so leaving one untouched costs precisely as much as an attempt that turns out wrong, and gains nothing.

MSQ carries its own trap in the other direction. With no partial credit, knowing two of four options are correct is worth nothing unless you can also rule on the other two. And an MSQ is not obliged to have more than one correct option: in GATE 2025 Physics, 3 of the 18 multiple-select questions had exactly one correct answer. Stopping after the first correct tick is how a well-prepared candidate scores zero.

One more line worth carrying: all 15 marks of General Aptitude are negatively marked, because the whole section is MCQ. It is the only part of the paper that is guaranteed to punish a guess.

3. What the qualifying mark actually is

Most people read the GATE cut-off as a target set by an examiner. It is not. It is a formula, and the brochure prints it:

Qualifying mark for the General category = max(25, min(40, μ + σ))

where μ is the mean and σ the standard deviation of the marks of everyone who appeared in that paper.

Two consequences follow immediately, and they change how you should read the number.

The cut-off is a description of the cohort, not of the paper’s difficulty. It is literally one standard deviation above the average mark. If it comes out low, the average candidate scored low; if it comes out high, they scored well.

And it is clamped between 25 and 40. A paper whose μ + σ falls below 25 publishes 25 anyway, and one whose μ + σ exceeds 40 publishes 40. When you see either of those exact numbers, the formula has been overruled by the floor or the ceiling, and the published figure tells you nothing about the cohort beyond “below 25” or “above 40”. The ceiling is recent: in GATE 2024 six papers qualified above 40, with one at 49.0. Since GATE 2025 no paper has exceeded 40.

Year	Registered	Appeared	Turnout	Cut-off (GEN)	OBC-NCL / EWS	SC / ST / PwD
GATE 2024	26,475	20,258	76.5%	32	28.8	21.3
GATE 2025	24,747	19,225	77.7%	26.8	24.1	17.8
GATE 2026	24,225	18,055	74.5%	25.5	22.9	17

The other two columns are not set separately. The brochure fixes them by ratio: OBC-NCL and EWS at 9/10 of the General mark, and SC, ST and PwD at 2/3 of it. Published figures are rounded to one decimal, so the arithmetic can look 0.1 out; the rule itself is exact.

What the Physics numbers actually say. The bar has fallen from 32 to 26.8 to 25.5 across three cycles, and 25.5 is only half a mark above the statutory floor. Because the cut-off is μ + σ, that is a statement about the candidates: the average Physics candidate plus one standard deviation is now scoring a quarter of the paper. It is not a statement that the paper got easier — if anything the opposite.

4. What a GATE score actually means

A GATE score is not your marks, and it is not a percentile. It is a linear rescaling with two fixed anchors, and once you know them the whole thing is readable:

• A score of 350 is exactly the qualifying mark. If you scraped through, you scored 350.
• A score of 900 is the average of the top 0.1% of candidates in your paper (or the top 10, whichever is larger).

Everything between is a straight line. The formula in the brochure is GATE Score = 350 + 550 × (your marks − Mq) ÷ (top-0.1% average − Mq), where Mq is the General-category qualifying mark.

This is why a score is comparable across papers in a way that marks are not. Two candidates on 700 in different subjects sit at the same point between their own paper’s bar and its top. It is also why the score depends on how well the best candidates did that year: if the top 0.1% average is lower, the same marks are worth more.

The scorecard is valid for three years. Institutes honour that; most public sector companies do not — their recruitment notices usually ask for the current year’s score. If a PSU job is the goal, the year you sit is part of the plan.

5. The syllabus, and the GATE 2027 rewrite

That figure shows the syllabus as it stood for GATE 2026: nine sections, flat, with no published weighting. For GATE 2027, IIT Madras has restructured it into eleven. This is the single most important thing on this page for anyone sitting the next cycle.

GATE 2026 — nine sections	GATE 2027 — eleven sections
1. Mathematical Physics	1. Measurements and Error Analysis — new
2. Classical Mechanics	2. Mathematical Physics
3. Electromagnetic Theory	3. Classical Mechanics
4. Quantum Mechanics	4. Thermodynamics and Statistical Mechanics
5. Thermodynamics and Statistical Physics	5. Electromagnetic Theory
6. Atomic and Molecular Physics	6. Optical Physics — new
7. Solid State Physics	7. Quantum Mechanics
8. Electronics	8. Atomic and Molecular Physics
9. Nuclear and Particle Physics	9. Solid State Physics
	10. Nuclear and Particle Physics
	11. Electronics

Two areas that were not sections before now are. Measurements and Error Analysis is placed first, which is a deliberate signal — it is experimental method, propagation of errors and data analysis, and it was previously scattered through the Electronics section at best. Optical Physics is likewise pulled out into its own section rather than living inside Electromagnetic Theory. Electronics moves from Section 8 to Section 11, the last position.

If you are preparing for GATE 2027 from a syllabus dated 2026 or earlier, those two sections are simply missing from your plan. Read the current one.

6. Who may sit it, and what it costs

Rule	What it says
Qualifying degree	Currently in the third year or higher of any undergraduate degree, or already holding one.
Degree subject	Need not match the paper. You choose the paper; the admitting institute sets its own subject requirements.
Age limit	None.
Attempts	No limit.
Two papers	You may sit up to two papers in one cycle, from the published list of allowed combinations.
Application fee (per paper)	₹1,000 for female, SC, ST and PwD candidates · ₹2,000 for everyone else. Both rise by ₹500 in the extended period.

The third-year rule is worth acting on rather than noting. You do not need the degree in hand, and a good score obtained in your third year is valid for three years — which covers the entire window in which you might want to use it.

7. What this paper is asking for

1. Attempt every MSQ and every NAT. Fifty of the 85 subject marks carried no penalty in GATE 2025.
2. Check every option on an MSQ. No partial credit — and three of the eighteen MSQs in GATE 2025 had exactly one correct option.
3. Prepare the two new GATE 2027 sections. Measurements and Error Analysis, and Optical Physics, are not in any pre-2027 syllabus you may be working from.
4. Mathematical physics before physics. It is Section 1 for a reason: it is the language the other sections are solved in.
5. Do not ignore General Aptitude. Fifteen marks, no physics in it, and all of it negatively marked.
6. Read the falling cut-off correctly. 32 to 25.5 in two years means the cohort scored less well, not that the paper got easier.

The syllabus is public and every candidate has the same one. What separates results is the penalty-free marks you collect and, this cycle, whether you noticed the syllabus changed.
