Hello Aspirant

The eligibility criteria for admission in the Bachelor of Computer Science is that the candidate must have passed their 12th grade from a UGC-recognised Board of Examination with Math and Computer Science or any equivalent subject (like IP). Their aggregate should cross 60% and the candidate must pass all their exams without any backlogs or compartments.

Since you had Computer Science in your 12th grade, and you hopefully will pass 12th with an aggregate of 60%, you are then eligible for BCA in any institute in India, including PU Chandigarh.
