The JEE Mains 2027 syllabus with weightage PDF has not been released yet by the National Testing Agency (NTA).
Based on the current pattern, students should expect the syllabus to closely follow the JEE Main 2026 syllabus, which covers Physics, Chemistry, and Mathematics from the Class 11 and Class 12 NCERT curriculum.
NTA usually releases the official syllabus PDF along with the information brochure, expected around October 2026.
- The syllabus is expected to remain the same as JEE Main 2026, since no fresh deletions have been announced.
- Mathematics carries the highest weightage from Calculus, Algebra, and Coordinate Geometry, which together make up close to 40% of the paper.
- The official syllabus PDF will be available at jeemain.nta.ac.in once released.
- NTA had reduced the syllabus in 2024 by removing several chapters to align it with the current NCERT pattern, and this reduced structure is expected to continue for 2027.
