Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

Based on analysis of previous papers, few topics carry more weightage than the rest of the topics. . In Physics, Modern Physics take the top slot with 5 questions. Heat and Thermodynamics, Optics, Current Electricity, Elcetrostatics get 3 questions each. Magnetic has 2 questions and the rest get 1 question each.

. For complete breakdown, please read our article: https://engineering.careers360.com/articles/jee-main-syllabus-weightage . Once you complete a topic, try to practise the concepts and write down the important points and paste them somewhere that you can see. Practise questions from that topic. Refer to books like:

Concepts of Physics by HC Verma

Fundamentals of Physics by Halliday, Resnick and Walker

Understanding Physics by DC Pandey

Problems in General Physics by I.E.Irodov

Understanding Physics by Freedman and Young

Problems and Solution of Physics by Shasti Bhushan Tiwari
