Hey Dhiraj, 

For applying to the course a candidate is required to have a 10+2 qualification/inter/or any other exam with an aggregate score of minimum 50% marks in total along with maths as a compulsory subject.So if you had maths in your 10+2 level you can easily apply for colleges government or private.The admissions are based on merit.While many colleges prefer entrance examination for the candidates.You should start applying for admission and i would suggest you to sit for the entrance exams.

Best of luck.
