JEE Main 2026 Session 2 began on April 2, and will continue until April 8, 2026. At this stage, clarity regarding the deleted syllabus becomes even more important. There have been no changes in the reduced syllabus for Physics, Chemistry, or Mathematics, so candidates should strictly follow the same syllabus that was applicable for Session 1.
Whether a student is aiming to improve their percentile from the January attempt or appearing for the first time, a focused strategy is essential right now. Instead of trying to revise the entire syllabus at the last moment, students should concentrate only on high-weightage topics and avoid deleted or low-impact chapters. This targeted approach during the ongoing April exam window can help you score well and reduce unnecessary confusion.

The National Testing Agency (NTA) has not removed any new topics this year. So, students should focus on the topics that were deleted in earlier years and are still not included. Studying only the useful topics will help students improve accuracy and make smart attempts. This strategy can help students score better in today’s exam and in future sessions.

JEE Mains 2026 Deleted Syllabus: Subject-wise
With the JEE Mains 2026 Session 2 exam underway, streamlining preparation is important. The deleted JEE syllabus applies to all three subjects—Physics, Chemistry, and Mathematics—based on official NTA notifications from 2024 and 2025. No new topics have been removed this year, so students should focus on the included portions and avoid spending time on irrelevant topics. Prioritizing these key areas can make a significant difference as exams continue from April 2 to 8, 2026.
