JEE Main Maths Chapter-wise Weightage: 225 Questions Counted from the April 2026 Papers

By the Ajay Vatsyayan Classes Home Tutors Team. Reviewed by Ajay Vatsyayan (B.Tech; Maths & Physics, IB and Cambridge IGCSE experienced). Last reviewed: 28 September 2026.

We counted every maths question in the nine official JEE Main 2026 Session 2 (April) B.Tech papers that NTA has published. That comes to 225 questions, and we sorted each one into the 14 units of the official syllabus. Coordinate geometry was the biggest single unit (32 questions, 14.2%) and integral calculus came next (26, 11.6%). Calculus as a whole (limits, differentiation, integration and differential equations) made up 53 questions, or 23.6%. Every shift had exactly two statistics and probability questions and exactly three from 3D geometry and vectors.

This JEE Main maths chapter wise weightage is our own count, not an NTA figure. NTA publishes the syllabus and the exam pattern, but it does not publish chapter-wise weightage. Below you will find the method, the full count tables, what the numbers mean for a 2027 aspirant, and where weightage stops being a useful guide. If you would like a tutor to turn this into a plan for your child, see our JEE maths tutor in Gurgaon page.

The short answer: JEE Main maths chapter wise weightage in 2026

Our count of the nine April 2026 shifts gives the following order. Each JEE Main maths question carries the same marks, so question share and mark share are the same.

• Coordinate geometry (straight lines, circles, conics): 32 of 225 questions (14.2%). There were 3 or 4 in every shift.
• Integral calculus (indefinite and definite integrals, area): 26 questions (11.6%). There were 2 to 4 in every shift.
• Complex numbers and quadratic equations: 20 questions (8.9%).
• Limits, continuity, differentiability and applications of derivatives: 18 questions (8.0%).
• Statistics and probability: 18 questions (8.0%). There were exactly 2 in every shift.
• Matrices and determinants: 17 questions (7.6%).
• Three-dimensional geometry: 17 questions (7.6%).

The smaller units were still present in almost every paper. Binomial theorem appeared in 8 of the 9 shifts, and differential equations and trigonometry each appeared in 8 of 9. So JEE Main maths chapter weightage tells you where to spend more time. It does not tell you what you can skip.

How we counted: papers, shifts and method

We wanted numbers a parent or student could check. So we used only NTA's own question papers and took nothing from coaching websites or memory-based recollections.

The source papers

On 28 September 2026 the official site, jeemain.nta.nic.in, listed the following JEE Main 2026 Paper 1 (B.E./B.Tech) question papers under "Question Papers". We downloaded and used all of them:

• B Tech 2nd Apr 2026, Shift 1 and Shift 2
• B Tech 4th Apr 2026, Shift 1 and Shift 2
• B Tech 5th Apr 2026, Shift 1 and Shift 2
• B Tech 6th Apr 2026, Shift 1 and Shift 2
• B Tech 8th Apr 2026, Shift 2

That is nine shifts. Each paper has 25 maths questions (20 multiple-choice in Section A and 5 numerical in Section B), so the total is 225. On the date we checked, the site did not list the January 2026 (Session 1) papers, so they are not in this count. If NTA publishes more papers, we will add them and update the "last reviewed" date.

The classification rules

1. Official units only. Every question was placed in one of the 14 maths units of the "Syllabus for JEE (Main) – 2026" published by NTA. We used NTA's unit names, not coaching chapter lists.
2. One unit per question. Each question was counted once, under the unit whose idea decides the answer. For example, a question that builds a quadratic out of a series but asks about its roots went to "Complex numbers and quadratic equations".
3. Ambiguity recorded, not hidden. 21 of the 225 questions (about 9%) mix two units. We still counted each one once, but we logged the second unit. Most of these mixed items sit in quadratic equations (6) and integral calculus (5). So treat a difference of one or two questions between units as noise.
4. Integral equations and area. Area-under-curve questions and "f defined by an integral" questions were counted in Integral Calculus (Unit 8), because the syllabus places "areas of the regions bounded by simple curves" there.

The question-by-question list (paper, question number, unit, subtopic and any ambiguity note) is kept by our team, so any count in this article can be traced back to the original paper.

Unit-by-unit count table (225 questions)

The units below appear in the same order as NTA's 2026 syllabus. "Range per shift" shows the fewest and most questions from that unit in any single shift.

Within coordinate geometry, the 32 questions split into 18 on conic sections (parabola, ellipse, hyperbola, including locus problems that end in a conic), 7 on circles and 7 on straight lines. Conics alone (18) got as many questions as the whole of Unit 7 or Unit 13, and only three complete units got more.

Shift-by-shift count: how stable is it?

A single shift can mislead. It is more useful to know how steady each area was from one shift to the next. Here the 14 units are grouped into six blocks so the pattern is easy to see.

Two things stand out. First, the blocks hardly moved. Calculus was 5 or 6 in every shift, 3D and vectors was exactly 3, and statistics and probability was exactly 2. Second, trigonometry swung the most, from 0 to 3, partly because trigonometric ideas often sit inside questions that belong to another unit. So a student who only drills the "big" chapters is taking a real risk: in a paper where trigonometry shows up three times, those questions cost 12 marks.

What the numbers mean: three priority tiers

We turn the count into three tiers. If you only want the JEE maths most important chapters, they are the ones in Tier 1. This is our reading of the data, not an official ranking. For a fuller chapter-by-chapter view that also covers JEE Advanced, read our guide to the most important maths chapters for JEE Main and Advanced.

From our tutors: the students who stall around the middle of the percentile table are usually not weak in one big chapter. They are "thin" across five or six small ones, such as binomial, differential equations, relations and inverse trigonometry. Each gap costs only one question, but together they add up to 20 marks or more. We usually fix Tier 3 first, because those chapters are quick to close.

What the 2026 questions actually tested, with worked examples

A count only tells you how many questions a unit got. This section describes what those questions asked, based on our reading of the same nine papers.

Coordinate geometry (32 questions)

Conics dominated. We saw parabola chords and focal chords, ellipses defined by eccentricity and a point, hyperbolas defined by foci and directrices, and many locus questions whose answer turns out to be a conic. The circle questions were mostly about chords, intercepts and the relation between a line and a circle. The straight-line questions covered triangle centres (incentre, orthocentre, circumcentre), angle bisectors and reflection.

Worked example (standard ellipse facts). For the ellipse x²/25 + y²/16 = 1, find the eccentricity, the foci and the length of the latus rectum.

• Here a² = 25 and b² = 16, with a > b, so the major axis lies along the x-axis.
• e = √(1 − b²/a²) = √(1 − 16/25) = √(9/25) = 3/5.
• Foci: (±ae, 0) = (±5 × 3/5, 0) = (±3, 0).
• Latus rectum = 2b²/a = 2 × 16/5 = 32/5.

Almost every 2026 conic question needed facts like these as a first step, before the real problem began. If they take you more than a few seconds, you lose time on every conic question. Our JEE maths PYQ strategy guide explains how to build that speed from previous papers.

Integral calculus (26 questions)

Definite integrals were the core. Properties such as a + b − x substitution, even and odd functions and periodicity came up again and again, along with the greatest integer and modulus functions inside integrals. There were also area-between-curves questions, often after a small functional-equation step, and a few integral equations that you solve by differentiating.

Worked example (the "King's property"). Evaluate I = ∫₀^π/2 sin x / (sin x + cos x) dx.

• Use ∫₀^a f(x) dx = ∫₀^a f(a − x) dx with a = π/2. Since sin(π/2 − x) = cos x and cos(π/2 − x) = sin x, this gives I = ∫₀^π/2 cos x / (cos x + sin x) dx.
• Add the two forms: 2I = ∫₀^π/2 (sin x + cos x)/(sin x + cos x) dx = ∫₀^π/2 1 dx = π/2.
• So I = π/4.

Limits, continuity, differentiability and derivatives (18 questions)

Typical questions asked you to count points where a function is not continuous or not differentiable (often with the greatest integer, modulus or max functions), to evaluate a limit with an unknown constant, or to find maxima and minima of a polynomial. None of these needed long algebra. They needed a clear picture of the graph.

Complex numbers and quadratic equations (20 questions)

Common patterns were relations between roots and coefficients, conditions on the nature of roots, and the modulus and argument of complex numbers, including loci such as |z − a| = |z − b|. This unit had the most mixed questions in our count, because quadratics often appear inside questions from other units. That is one more reason to make it automatic.

Matrices and determinants (17 questions)

Nearly every shift had a system of linear equations with a condition such as "infinitely many solutions" or "no solution", plus a question on adjoint and determinant properties.

Worked example (consistency of a system). For which λ and μ does the system x + y + z = 6, x + 2y + 3z = 10, x + 2y + λz = μ have infinitely many solutions?

• Subtract the second equation from the third: (λ − 3)z = μ − 10.
• For infinitely many solutions this must reduce to 0 = 0, so λ = 3 and μ = 10. As a check, the coefficient determinant works out to λ − 3, which is zero at λ = 3.
• If λ = 3 but μ ≠ 10, you get 0 = (non-zero number), so there is no solution. If λ ≠ 3, there is exactly one solution.

Statistics and probability (18 questions, exactly 2 per shift)

Each shift had one statistics question (mean, variance, standard deviation or mean deviation, often "find the missing observation") and one probability question (conditional probability, Bayes' theorem or a counting-based probability).

Worked example (how variance behaves). The observations 2, 4, 6, 8, 10 have mean 6. Their variance is (16 + 4 + 0 + 4 + 16)/5 = 8. If each observation is multiplied by 3 and then increased by 1, the new mean is 3 × 6 + 1 = 19. The new variance is 3² × 8 = 72, because adding a constant does not change spread. Knowing this rule saves several minutes of recalculation.

3D geometry and vectors (27 questions, exactly 3 per shift)

3D questions were almost all about lines: the foot of a perpendicular, the image of a point in a line, the shortest distance between skew lines, and the angle between lines. This matches the 2026 syllabus, which lists lines and skew lines under Unit 11. Vector questions used dot and cross products, often to find an area or a projection.

Section B (numerical) questions: where they came from

Section B questions have no options to eliminate, and the 2026 bulletin says wrong numerical answers also lose a mark. So it helps to know where they came from. Across the 45 Section B maths questions in our nine papers:

• Coordinate geometry supplied 9, the most of any unit.
• Sets, relations and functions supplied 6. Counting the elements of a relation, or checking whether it is transitive, suits an integer answer.
• Integral calculus supplied 5 and limits and derivatives supplied 4.
• The remaining 21 were spread over ten other units, with no more than 3 from any one of them.

From our tutors: students often treat "relations" as a one-lecture topic because it is short in the textbook. In these papers it turned into integer-answer counting questions, where one missed ordered pair gives the wrong number and costs a mark. We teach these as small listing exercises done by hand before any shortcut, and that is where the accuracy comes from.

What this analysis cannot tell you

Honest limits matter more than decimal places:

• It covers one session. Nine April 2026 shifts are a solid sample, but they are not the January shifts and they are not 2027. Question setters can shift the balance.
• Classification is a judgement call. About 9% of questions mix units. Another person might move a few questions, which would change a unit's count by one or two, but it would not change the tiers above.
• Weightage is not difficulty. A unit with two easy questions can be worth more to you than a unit with four hard ones. Your own accuracy matters as much as the count.
• The syllabus is the real boundary. The count shows emphasis, while the official syllabus defines what can be asked. Check the current "Syllabus for JEE (Main)" and Information Bulletin on the NTA website every year. Our JEE maths syllabus: Class 11 vs Class 12 guide explains how the units are spread across the two years.

Turning weightage into a 2027 study plan

This is how our tutors use a count like this with a JEE 2027 student. The facts below come from the JEE Main 2026 Information Bulletin, so check the 2027 bulletin when NTA releases it.

Know the paper you are planning for

In the 2026 bulletin, Paper 1 maths had 20 multiple-choice questions (Section A) and 5 numerical-value questions (Section B), for 100 marks. Each correct answer earned +4 and each incorrect answer −1, in both sections. The paper lasted 3 hours for all three subjects. NTA also issued a notice on 2 November 2025 saying that calculators in any form are not allowed in JEE (Main), even though the testing platform has one. This matters for planning: accuracy is worth more than attempting everything, and your arithmetic has to be reliable without a calculator.

Allocate time by tier, then by personal weakness

1. Close Tier 3 gaps early. Binomial, differential equations, relations and inverse trigonometry are short chapters. A focused week on each usually secures about one question a paper.
2. Build Tier 1 in depth. Give coordinate geometry and calculus the most hours, but in layers: standard results first, then mixed problems. Our PYQ strategy guide shows how to use the official papers to do this.
3. Keep Tier 2 warm. Matrices, 3D, statistics and probability repeat their question styles, so a small weekly set keeps them secure without taking much time.
4. Re-weight after every mock. After each full test, mark every lost question by unit. If one unit keeps costing you marks, it moves up your list, whatever the table above says.

A simple weekly split for Class 12 students

These shares are a starting point from our tutors' experience, not a rule. A student who is already strong in calculus should move time to wherever the error log points.

Frequently asked questions

Which chapter has the highest weightage in JEE Main maths?

In our count of the nine April 2026 papers, coordinate geometry (Unit 10) had the most questions: 32 of 225, or 14.2%. Integral calculus was second with 26 (11.6%). If you group limits, derivatives, integrals and differential equations together as calculus, that block was larger still, with 53 questions (23.6%).

Does NTA publish official chapter-wise weightage for JEE Main maths?

No. NTA publishes the syllabus, the Information Bulletin (pattern and marking) and the question papers. Any chapter-wise weightage, including ours, is an analysis of past papers. That is why we name the exact papers and method we used.

Which JEE Main maths chapters can I skip?

We would not skip any. Even the smallest unit in our count, binomial theorem, appeared in 8 of the 9 shifts. Trigonometry and differential equations were also each missing from only one shift. Skipping a unit usually means giving up about one question in most papers, and these short chapters are often the quickest marks to secure.

How many maths questions are there in JEE Main, and are they all compulsory?

The JEE Main 2026 Information Bulletin lists 25 maths questions in Paper 1: 20 multiple-choice (Section A) and 5 numerical-value (Section B), for 100 marks. Negative marking of −1 applies to incorrect answers in both sections. Check the bulletin for your year, because the pattern can change.

Is Class 11 or Class 12 maths more important for JEE Main?

Both matter, and the units do not split neatly by class. Coordinate geometry, complex numbers and quadratics, sequences and statistics are mostly Class 11 topics. Integral calculus, differential equations, matrices, vectors and 3D are mostly Class 12. Tier 1 contains both kinds, so a student who neglects Class 11 while studying for Class 12 boards is taking a risk.

Will the JEE Main 2027 maths weightage be the same as 2026?

No one can promise that. The 2026 shifts were very consistent with each other, which suggests the broad balance is stable, but the setters are not bound by it. Prepare the full official syllabus, use weightage to set priorities, and check the 2027 syllabus and bulletin when NTA releases them.

How should I use this weightage if my mock scores are low?

Start with accuracy, not coverage. Pick two Tier 1 units and two Tier 3 units, practise official questions from them until your accuracy is high, then add more. Negative marking applies to every question, so fewer confident attempts often score better than many guesses.
