I am struggling in Physics and Chemistry.

Well, if you have Physics, Chemistry, and Mathematics, all three in your Bachelor's degree you should first understand and analyze that which subject you like the most and you are highly interested in. Then devote atleast a year and evaluate the scope of M.Sc in that particular subject, study it and then select the subject. Don't be in a rush, take your time.

The physics section will hold 30 marks weigtage in the SITEEE question paper. There will be 15 MCQs out of the class 11th and 12th physics syllabus of CBSE, each of 2 marks.

All the topics mentioned in the SITEEE exam syllabus are important. Some of the most important topics out of the SITEEE physics syllabus are Kinematics, Laws of Motion, Work, Energy, and Power, Gravitation, Thermodynamics, Oscillations and Waves, Electrostatics, Current Electricity, Magnetism, Electromagnetic Induction, Optics (Ray and Wave), the Dual Nature of Radiation and Matter, Atoms and Nuclei, and Semiconductors.

The SITEEE syllabus for physics is based on the class 11tha dn 12th syllabus of the CBSE curriculum.

For the JEE Advanced physics section, toppers and experts refer to the following books:

• Understanding Physics by DC Pandey
• Practice Book Physics for JEE Main and Advanced by DC Pandey
• NCERT Physics Class 11 and 12
• Problems in General Physics by I. E. Irodov
• Concepts of Physics by H. C. Verma
• Wiley's Halliday / Resnick / Walker Physics for JEE (Main & Advanced) by Halliday, Resnick and Walker
