Hello
Yes, you can apply for admission. Admission to B.Sc (Hons) is done on the basis of marks of candidates in the qualifying examination. Every college declares it own cutoff for admission. If you meet the required cutoff and fulfill the other criteria required for admission then you can get a seat.
Registrations for admission to UG courses start in the last week of May. You can refer to the information bulletin using the link below for detailed information:

Good Luck!
