NDA Physics Syllabus 2026: Complete Guide for Aspirants 

The NDA Physics syllabus is a crucial section of the GAT syllabus as it assesses the candidate’s knowledge of fundamental sciences and their applications.

According to official exam pattern released by UPSC in the NDA exam, the GAT paper is of 600 marks and the Science section of this paper comprises questions based on Physics, Chemistry and Biology.

Physics is a scoring subject as most of the questions are not based on numerical problems and are based on the fundamental concepts for NDA aspirants.

A good knowledge of Physics aids candidates to enhance their GAT score and also enhances their logical thinking skills which is essential for defence training.

What is the NDA Physics Syllabus? 

The important concepts from school-level Physics, primarily based on the NCERT Physics class 11 and class 12 topics, are included in the NDA Physics syllabus.
