Hello Geeta,

Candidates willing to apply for the B. Sc Computer Science need to meet the following minimum eligibility criteria:

• Higher Secondary (10 + 2) qualification from a recognized educational Board with Mathematics as one of the main subjects.
• A minimum aggregate score of 45% at the 10+2 level.
• Candidates awaiting their 10+2 exam results may also apply on a provisional basis. Admission is confirmed on the basis of final results.

Maths in 11th and 12th is commandeered, for B Sc in Computer Science whether you take computer science or biology that does not really matter.

However, it depends on the decision on the institution and may differ from college to college.

Hope this helps.
