Hey.

The eligiblity criteria for admission in the course of Computer Science differs from college to college. Each institute has it's own criteria for admission. Various colleges would require you to pass Class 12th board examination with Science subejcts in order to be eligible. A few colleges only require you to pass class 12th from any stream. Hence for this course taking Maths is not compulsory. But in some colleges the criteria may require you to have some specific subejcts even maths. So you must keep in mind theprobable colleges.

Best of luck
