BSc Computer Science is a popular degree among the students nowdays. The eligibility criteria or the requirements vary from one Institute to other. However most of the Institutes ask for having passed in Physics, Chemistry, Mathematics and English for Bachelor of science in Computer Science. The candidate must have passed with at least 50% marks in 12th. Also the minimum marks criteria also varies. Whereas some colleges only require passing of 10+2. There is no subject barrier. But as Computer science deals with Mathematics and Statistics so most of the colleges ask for having at least Mathematics in intermediate level. This totally depends on the Institute you are applying for.
