IIT JAM Geology (GG): The Broadest Paper in the Exam

Geology sits in the middle of IIT JAM by almost every measure: 213 seats at the IITs, a mid-range cutoff, and a candidate pool that is neither the largest nor the smallest. What it does not have is a middling syllabus. GG is the broadest paper in the exam — eight units running from the composition of the Earth’s core to the interpretation of a satellite image.

This article covers the GG paper specifically: where it sits, 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 Geology paper sits

Geology is one of the few papers that sits mid-table on both columns at once, which makes it a useful reference point for reading the rest of the chart. Physics has more than four times its seats at a lower cutoff. Economics has a quarter of its seats at twice the cutoff.

The two columns are set by different things — how many M.Sc. programmes exist in that discipline, and how hard that year’s paper turned out to be. Neither predicts the other, and reading one as a proxy for the other is how candidates pick the wrong paper.

2. The syllabus

The GG syllabus covers standard B.Sc. geology, and its defining feature is range rather than depth. In one three-hour paper you can be asked about radiometric dating, the morphology of a brachiopod, the classification of a metamorphic rock, and the interpretation of a geological map.

Two units behave differently from the rest and are worth planning around.

Structural Geology is drawn as much as it is written. Dip and strike, outcrop patterns, the rule of V’s, cross-section construction and stereographic projection are practised skills, not facts to revise. They are also the ones most reliably tested in Section C, because they produce clean numerical answers.

Palaeontology and Stratigraphy reward systematic memory more than anything else in the syllabus — fossil groups, the geological time scale, Indian stratigraphic units. That makes them the cheapest marks available to a candidate willing to be methodical, and the easiest to lose by leaving them to the last week.

3. 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 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.

4. What five years of cutoffs say

JAM year	General	OBC-NCL / EWS	SC / ST / PwD
JAM 2021	34.65	31.18	17.32
JAM 2022	Not available
JAM 2023	31.04	27.94	15.52
JAM 2024	33.09	29.78	16.55
JAM 2025	21.06	18.95	10.53

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 Geology cutoff has ranged from 21.06 to 34.65 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 matters more in Geology than in most papers. A geology M.Sc. generally expects geology in the degree behind it, and the specific requirements differ by institute. Read the minimum educational qualification for the programmes you actually want before you register.

6. What the paper is asking for

1. Breadth before depth. Eight units in one paper means no unit is safe to skip, and unusual depth in one cannot cover a hole in another.
2. Practise the structural geology, do not read it. Maps and projections are the part of this syllabus that only improves by being drawn.
3. Be systematic about palaeontology and stratigraphy. They are the most memorisable marks in the paper.
4. Attempt everything in Sections B and C. Half the paper carries no penalty for being wrong.

Unit-level preparation and attempt strategy are separate articles. This one is the map.
