Hey Hardik,

The best 4 subject for B.sc Maths are calculated on the aggregate of the following subjects:

• One language subject
• Mathematics
• 2 best elective/academic subject

The selection for B.Sc(Hons) in Chemistry will be made according to the aggregate of the following 3 subjects:

• Physics
• Mathematics
• Chemistry

Sorry to say you have to include physics in both as physical education plays no role in Science.

Hope this helps, all the best.
