Hey !

I'm sorry to say but you can't do Bsc computer science without maths in DU

The eligibility criteria is You need minimum 60% marks in maths in 12th and for admission you have to also look for cut-offs In DU cut-offs are very high.

But You can do BCA, you may have to give separate maths exam with your sem 1 exams.

I hope this information might be helpful for you,

All The Best !!!
