According to the official website, the JEE Main chapter-wise weightage 2026 has not been revised. At this stage, the most reliable resource for candidates is the previous year’s study material and chapter-wise weightage. These provide valuable insights into the topics that carried maximum marks last year and are, therefore, likely to remain important for the upcoming exam.
A well-planned JEE Main 2026 preparation strategy can significantly improve scores if students focus on topics that frequently appear in past exams. By reviewing the chapter-wise weightage for Physics, Chemistry, and Mathematics from the JEE Main 2025 question papers, aspirants can clearly identify high-priority chapters. This helps them decide which areas require more practice and which topics consistently dominate the paper.
In short, analyzing the previous year’s chapter distribution enables candidates to streamline preparation, concentrate on repeated topics, and maximize their chances of scoring well in JEE Main 2026.
JEE Mains is conducted by NTA annually for engineering course admissions. Various candidates will apply for the JEE Main 2026 to get their dream colleges. The complete overview of JEE Main 2026 is given below in the table.

Key high-weightage chapters for Mathematics in JEE Main 2026 include:
For Physics and Chemistry, frequent high-weight topics are typically Modern Physics, Thermodynamics and P-Block elements, as indicated by past trend analyses
The difficulty of JEE Main 2026 is expected to remain moderate, similar to previous years. While the overall difficulty may not be significantly higher, increased competition and a shift towards more concept-based questions could make it feel tougher for some aspirants.
There have been no significant changes to the JEE Main 2026 syllabus. The syllabus structure remains consistent with the reduced version introduced in 2024. The exam will continue to follow the same syllabus spanning Class 11 and 12 concepts in Physics, Chemistry, and Mathematics.
In one of the JEE Main 2025 sessions held in Chandigarh, Vansh Goyal and Mehul Talwar both achieved an impressive 99.97 percentile.
