NEET Physics Syllabus: Chapter-Wise Weightage

NEET Physics Deleted Syllabus

There are changes to the NEET syllabus, including for physics. The National Medical Commission (NMC) and National Testing Agency (NTA) have revised the syllabus for NEET (UG) to align with updated NCERT textbooks and content being taught in various school boards. Some topics that were not part of the NCERT syllabus or not taught in schools have been removed, while core concepts remain a focus​.

Major Changes:

1. Removed Topics:
   • Topics not covered by most school boards or NCERT textbooks have been eliminated. These include some advanced or less-relevant concepts for undergraduate medical education.
2. Updated Focus Areas:
   • Emphasis has been placed on core concepts in Physics to ensure uniformity and clarity across all boards. For example, topics from mechanics, thermodynamics, and optics have been retained with detailed subtopics.
3. Class-Wise Syllabus Overview:
   • The syllabus is divided into Class 11 and Class 12 portions, with no significant changes in structure but some minor adjustments in content to align with NCERT.

The deleted topics from both class XI and XII syllabus are mentioned below.

Deleted Topic from Class XI Physics Syllabus
