JEE Main Syllabus 2026: Detailed JEE Main Mathematics, Physics, and Chemistry Syllabus (NTA Updated)

The JEE Main syllabus is the blueprint of the exam and is crucial for every JEE aspirant. Every year nearly 12 lakh students enter the JEE competition, and only 2% make their way to the top. The first step towards cracking the exam is to understand what to study. The JEE Main syllabus is released and updated by NTA every year, which we have discussed in detail here.

The JEE Main syllabus is heavily based on NCERT concepts. This blog includes the updated and revised JEE Main syllabus for the year 2026. We will break down the detailed syllabus of all three subjects: mathematics, physics and chemistry.

What is JEE Main 2026 Syllabus?

JEE Main syllabus is the officially released document carrying list of topics based on which the question paper of JEE Main exam will be set. The JEE Main exam has 3 papers. Paper 1 is for the B. Tech course, Paper 2A is for the B. Arch, and Paper 2B is for the B. Planning course. The syllabus differs lightly for all three papers as the paper pattern varies according to the course. NTA is the conducting body of the JEE Main exam, and NTA releases the syllabus as well.

The JEE Main syllabus forms the foundational block behind the JEE Main preparation strategy. The majority of the JEE Main syllabus is directly from the curriculum of classes 11 and 12.

• The paper 1 syllabus for the B.Tech course includes physics, chemistry and mathematics.
• The paper 2A syllabus for the B.Arch course includes physics, drawing and aptitude.
• The paper 2B syllabus for the B.Planning course includes mathematics, aptitude and planning subjects.
