 GATE Exam Pattern GATE Syllabus GATE Paper Analysis

Physics is the natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force. GATE exam for Physics will be of 100 marks. The duration for the exam is three hours. In this article, we are providing the complete syllabus for GATE Physics.
