Most JEE Main maths advice starts with chapters. It is worth starting one step earlier, with how the paper is actually scored – because the marking scheme changes how you should attempt it.
This guide follows the official JEE Main 2026 Information Bulletin from the National Testing Agency (NTA). The 2027 bulletin has not been published yet; we will update this page when it is. You can see the full structure, syllabus units and sources on our JEE Main Maths guide.
The paper at a glance
JEE Main Paper 1 (for B.E./B.Tech) is a 3-hour computer-based test with three subjects – Mathematics, Physics and Chemistry – carrying equal weightage. In the 2026 pattern:
- the whole paper has 75 questions and 300 marks
- Mathematics has 25 questions worth 100 marks
- Section A has 20 multiple-choice questions (80 marks)
- Section B has 5 numerical-value questions, where you type the answer (20 marks)
The 2026 bulletin did not include optional questions: all 25 maths questions are there to be attempted.
How each question is marked
Every maths question carries the same marking in both sections:
- +4 for a correct answer
- −1 for an incorrect answer
- 0 if you leave it unanswered
That last point matters. Many students assume numerical questions carry no negative marking. Under the 2026 rules they do: a wrong numerical answer costs a mark just like a wrong MCQ.
What the scoring means for strategy
With +4/−1 marking, a pure guess between four options is still slightly positive on average – but a careless wrong answer to a question you could have solved costs you five marks of swing (the four you missed plus the one deducted). In practice the bigger lever is accuracy on questions you know how to do.
A sensible approach in the exam:
- First pass: answer every question you can do confidently and quickly.
- Second pass: return to questions that need longer working.
- Final pass: decide on the remaining ones. Attempt a question if you can eliminate options or are reasonably confident of the numerical answer; leave it if you would be guessing blind.
For the numerical section, check units and rounding instructions on screen – a correct method with a sloppy final value scores the same as a wrong one.
A worked example: two students, the same score
Consider two students in a maths mock:
- Student A attempts all 25 questions and gets 18 right and 7 wrong: 18 × 4 − 7 × 1 = 65 marks.
- Student B attempts 20 questions and gets 17 right and 3 wrong: 17 × 4 − 3 × 1 = 65 marks.
Same score, very different stories. Student A needs to cut wrong answers – those 7 errors cost 7 marks directly and 28 marks of missed opportunity. Student B is accurate but slow or unsure on five questions, so the work is speed and coverage of weaker units. A good mock analysis separates these two problems, because the fixes are different.
Budgeting time for maths
The paper is 3 hours for three subjects. Many students aim for roughly an hour on maths, which works out to a little over two minutes per question on average. In practice the time is uneven: some multiple-choice questions take under a minute, while a long calculus or coordinate geometry question can take five. That is why the first-pass strategy matters – it protects time for the questions that need it.
Practising for the numerical section
Section B questions have no options to check against, so the habits that help are:
- Write clean working even in a computer-based test – most numerical errors are arithmetic slips, not wrong methods.
- Estimate first. A quick estimate of the size of the answer catches many errors before you type.
- Re-read the question once you have an answer, to confirm you answered what was asked (for example, the sum rather than one root).
Why maths carries extra weight
Maths is a third of the paper, but it also matters beyond its 100 marks. When two candidates have the same overall score, NTA's tie-breaking uses the Mathematics NTA score first. In a close rank band, a few extra marks in maths can decide the order.
Two sessions, best score counts
JEE Main runs in two sessions. In 2026 they were held in January and April, and the better NTA score is used. NTA's exam calendar lists JEE Main 2027 Session 1 for 22–24 and 28–30 January 2027 (tentative).
The two-session system gives students a real second chance: treat the January attempt as a full performance, then use the gap to repair the specific units that cost marks. Our JEE Main practice plan and JEE maths revision plan pages cover this in more detail.
How Maths Bodhi uses this in teaching
When we work with JEE students in Gurgaon, we track two numbers in every mock: marks scored and marks lost to wrong answers. The second number is usually where the quickest improvement comes from – rushed algebra, sign errors and misread numerical instructions.

Frequently asked questions
- How many maths questions are there in JEE Main?
- In the 2026 pattern, the Mathematics section of Paper 1 has 25 questions: 20 multiple-choice questions in Section A and 5 numerical-value questions in Section B, for 100 marks.
- Is there negative marking for numerical questions in JEE Main?
- Yes. Under the official 2026 bulletin, both sections are marked +4 for a correct answer and −1 for an incorrect answer, with 0 for unanswered questions.
- Does maths affect the JEE Main tie-break?
- Yes. If candidates have the same total, NTA uses the Mathematics NTA score first to break the tie.
