Mathematical Reasoning is one of the JEE Main 2027 Maths deleted topics that has been removed from the JEE Main Maths syllabus.
The whole chapter was removed in the NTA revision that took effect from JEE Main 2024.
- The 14 Maths units in the JEE Main 2027 syllabus do not list Mathematical Reasoning or Mathematical Induction, which were both removed as whole chapters.
- The 2027 syllabus is reported as unchanged from 2026, so the earlier topic-level cuts continue.
- Statistics and Probability stays, but Bernoulli trials and the binomial distribution are out.
- Students should drop Mathematical Reasoning from their plan and spend the time on Calculus, Coordinate Geometry and Algebra instead.

Key Summary
- The JEE Main 2027 syllabus was published on jeemain.nta.nic.in around 24 to 25 October 2026 and has 14 Maths units in Paper 1.
- The Maths deletions come from the 2024 to 2025 revision and are widely listed by coaching and portal pages, since NTA publishes only the retained units.
- No source reviewed reports any new Maths cut for 2027, so earlier deletions carry forward.
- Always cross-check the official syllabus PDF, because deleted sub-topics are not listed there by name.
Is Mathematical Reasoning in the JEE Main 2027 Syllabus?
No. Mathematical Reasoning has been deleted from JEE Main 2027, and no questions from it will be asked.
- The chapter, which covered statements, logical connectives and truth tables, was removed as an entire chapter in the 2024 revision.
- The NTA unit list for 2027 has no unit with this name, which matches the earlier removal.
- Mathematical Induction was removed in the same revision, so students can skip both.

Ques. How many Maths units are there in JEE Main 2027?
Ans. There are 14 Maths units in Paper 1, along with 20 units in Physics and 20 units in Chemistry. The Maths section has 20 MCQs and 5 numerical questions for 100 marks.
How to Prepare After the Maths Deletions
Students should treat the 14-unit list as the full syllabus and skip any chapter or sub-topic listed as deleted.
- Skip Mathematical Reasoning and Mathematical Induction entirely, and use the saved time for Calculus and Coordinate Geometry.
- Solve previous year questions carefully, since older papers may include deleted topics that should be ignored.
- For units with partial deletions, such as Vector Algebra and 3D Geometry, check each sub-topic against a NCERT-aligned book before studying it.
Ques. Should I solve old JEE Main papers that include Mathematical Reasoning?
Ans. Yes, but skip questions from deleted topics. Papers from 2023 and earlier include Mathematical Reasoning questions that are no longer relevant.
