Hello Aspirant

The eligibility criteria for getting admitted to a BSc Computer Science program is that you should have a computer science or related subject in your 12th grade. Since you had that in your 12th grade, you are eligible to take admission in BSc CS. You just need to appear for the CUET UG exam that is held every year around the month of March or April. Keep yourself updated by checking the NTA website regularly for the form's release dates.

Hope this helps
