Key Highlights of JEE Mains 2026 Syllabus

Before you start studying, check these important points about the syllabus:

• Based on NCERT: The JEE Mains 2026 Syllabus follows Class 11 and 12 NCERT books. It covers Physics, Chemistry, and Mathematics. The reduced syllabus lets you focus on core concepts.
• No New Cuts This Year: NTA hasn't removed any new topics for 2026. The deleted syllabus includes only past reductions. So the current official syllabus is final.
• Past Changes Still Apply: Topic deletions from 2024 and 2025 remain in effect. For example, scalars and vectors were cut from Physics in 2025. Chemistry and Maths also saw similar changes in 2024.
• Update Your Study Plan: Adjust your preparation based on these deletions. Don't waste time on removed topics. Focus only on what's in the current syllabus. This makes your preparation more efficient and targeted.
