HELLO,

See admission criteria and eligibility can vary from college to college as every colleges have its own set of rules so you have to mention the name of the college in which you are intersted for admission so that i can help you with specific details

Generally most of the colleges requires 50 percent in your class 12th for admission and some college conduct their own entrance exams for admission and on the basis if entrance test marks they give admissions

Hope this Helps!
