Hi

Depends on the university. Though the general eligibility is Physics, chemistry and maths mandatory.  But in DU to study BSc (Hons) Computer Science, an applicant should have had Mathematics and Computer Science in their plus-two course. Though it is not necessary to add the subjects in the best-of-four calculation, scoring at least 60 per cent or more in Mathematics is mandatory. The university information bulletin states that selection for the course will be made on the basis of the best-of-four subjects that include one language, Mathematics and any two subjects out of Physics, Chemistry, Computer Science and Informatics Practices.

Students from other streams need to include one language, Mathematics, and two other academic subjects. But they will face a deduction of 2 per cent.

There might be some additional eligibility the institute might be asking so try enquiring about it.

Hope this helps.
