hello sunil 

first of all it can be seen that du 's cutoffs remains pretty high every year . getting into physics and maths honours at this percentage would be quite tough for you .you can get into some colleges for these courses if you belongs to any reserved category . however if are getting in between them then go as per your interst or you can also chose maths if you are job oriented .(please clear in the cments is it mathematical science or maths honours?)
