JEE Mains 2026: Deleted Chapters & Reduced Syllabus

For JEE Mains 2026, the syllabus remains reduced as per the major changes introduced in 2024, with some minor adjustments made in 2025. The National Testing Agency (NTA) has not announced any further reductions or additions for 2026 as of now, so the deleted chapters and topics from previous years still apply.

Below is a summary of the chapters and topics that have been removed from the JEE Mains syllabus for 2026, based on the most recent and reliable sources:
