JEE Main Syllabus for Physics: Important topics, Weightage Analysis
Latest Update: As announced by the HRD Minister Mr Ramesh Pokhriyal on 5th May, 2020, the JEE Main examination will be conducted from 18th – 23rd July, 2020.
JEE Main Syllabus for Physics is provided by the exam conducting authority. This year NTA has made some change in the pattern of the examination. Physics section will hold 25 objective type questions.
JEE Main Syllabus for Physics contains two sections – A and B. Section A pertains to the Theory Part which holds 80% of the total weightage and Section B contains Practical Part (Experimental Skills) having 20% weightage.
