IIT JAM Physics (PH): The Paper, the Seats and the Cutoffs

Physics is the biggest paper in IIT JAM. It carries 952 of the 3,037 M.Sc. seats at the IITs — nearly a third of everything the exam admits to — and in 2025 it had one of the lower qualifying cutoffs of the seven. Those two facts together make it the most accessible of the large papers, and they are worth understanding before anything else.

This article is about the PH paper specifically: where it sits among the seven, how it is built and marked, what the syllabus contains, and what five years of cutoffs actually say.

If you have not sat IIT JAM before, the general guide to the exam covers the rules that apply to all seven papers — the marking scheme, eligibility and how admission actually works. This page assumes them.

Which year is this data from? Every figure here is from the IIT JAM 2025 cycle — the 2025 seat matrix, and the qualifying cutoffs declared with the 2025 result — with the cutoff series running back to JAM 2021. The exam pattern, marking scheme and eligibility rules are as they stand now.

This page is updated after each year’s result rather than replaced, so the older figures stay here beside the new ones. A single year tells you where the bar was; five years tell you how far it moves, which is the more useful thing to know while you are preparing.

1. Where the Physics paper sits

Read the two columns against each other and the useful thing is that they barely agree. Physics has the most seats and a below-average cutoff. Economics has the fewest seats and the highest cutoff. Biotechnology has almost the fewest seats and a cutoff well above Physics.

A big paper is not an easy paper and a small one is not a hard one. Seats and cutoffs are set by different things — how many programmes exist in that discipline, and how hard that year’s paper turned out to be — and reading one as a proxy for the other is how candidates pick the wrong paper.

2. The paper itself

Every JAM paper has the same three sections, and the difference between them decides more of your score than most candidates realise.

Section	Type	Questions	Marks	Negative marking
A	Multiple choice, one correct	30	50	−1/3 and −2/3
B	Multiple select, one or more correct	10	20	None
C	Numerical answer, type the value	20	30	None

Fifty of the hundred marks carry no penalty for a wrong answer. In Sections B and C a blank and a wrong answer score identically, so there is no defensive reason to leave a numerical question untouched. Section A is the only place a guess costs you anything — and a wrong 2-mark MCQ swings 2⅔ marks against you once you count the marks you did not get.

Section B has one more rule worth stating plainly: there is no partial credit. Select two of three correct options and you score zero, exactly as if you had selected nothing.

3. The syllabus

The PH syllabus is standard B.Sc. physics, and its structure has one feature worth planning around: Mathematical Methods is not a unit you finish and move past. Vectors, matrices, differential equations and calculus are the tools every other unit is solved with, so weakness there does not cost you one unit’s marks — it costs you a fraction of all of them.

The other structural point is that Solid State Physics and Electronics sit at the end of most degree courses and at the end of most candidates’ preparation, and together they carry a meaningful share of the paper. They are also the most self-contained units in the syllabus, which makes them the cheapest marks available to somebody who has run short of time.

4. What five years of cutoffs say

JAM year	General	OBC-NCL / EWS	SC / ST / PwD
JAM 2021	19.91	17.92	9.96
JAM 2022	26.05	23.45	13.03
JAM 2023	18.44	16.60	9.22
JAM 2024	19.63	17.67	9.81
JAM 2025	14.66	13.19	7.33

The General column is the figure declared with each year’s result. The other two are not set separately — JAM fixes them at 90% and 50% of the General cutoff, so they follow from it exactly, and you can always derive your own category’s number that way.

Read the series rather than the latest bar. Over these five years the Physics cutoff has ranged from 14.66 to 26.05 out of 100, and the reason is that the bar is set after the paper — it measures how that year’s cohort scored. A cutoff that falls means the paper was harder, not that fewer people wanted the seats; a cutoff that rises means it was kinder.

That is also why last year’s figure is a poor target. It is a description of a paper you will not sit.

And in every year, this is the bar to appear on the merit list — not the bar for a seat. Admission is decided later by All India Rank against each programme’s closing rank, which is published during counselling.

5. Who may sit it

Rule	What it says
Qualifying degree	A bachelor’s degree. Final-year students may apply and produce it at admission.
Minimum marks to apply	The old percentage cut-off has been relaxed — a pass in the degree is what is needed to appear.
Age limit	None.
Attempts	No limit.
Degree subject	Need not match the paper you sit — but the programme you apply to sets its own subject requirements.

That last row is the one to act on. Sitting the paper is open to anybody with a degree; being admitted to a specific M.Sc. programme is not. Each institute publishes a minimum educational qualification for each programme — which subjects you must have studied, and at what level — and those are the lists to read before you register, not after your result.

6. What the paper is asking for

1. Mathematical fluency before physics. The syllabus puts Mathematical Methods first for a reason: it is the language the other seven units are written in.
2. Finish the back of the book. Solid State and Electronics are late in the course, self-contained, and routinely under-prepared — which makes them the best marks-per-hour in the syllabus.
3. Attempt everything in Sections B and C. Half the paper carries no penalty. A blank there is a mark you chose not to try for.

Which topics to study in what order, and how to attempt three hours of this paper, are questions for their own articles. This one is the ground you are standing on.
