Hii!
The basic eligibility criteria for BSC states that the candidate must have passed class 12th with minimum 50- 60% marks in science stream from a recognised board of education. So, you can't do BSC without science stream in class 12th.
However, since you have studied commerce in class 12th, you must have studied mathematics too. That opens some options for you in computer field. You can apply into BCA, IT etc., Courses as per their eligibility criteria if you have studied mathematics in class 12th.
Hope this helps.
Good luck!
