Greetings of the day dear candidate!

Admissions into various colleges will start right after board exams of class 12th will end.  Also, the admisisons for various different courses  have some particular eligibity criteria.  So, you should wait for atleast till June last week for admission  procedure to start.

See, if you want to take admisisons on direct basis then you can simply visit the college and fill the form and pay the fees but for that you need your class 12th marksheet. So that is why you should wait till the examination is completed for class 12th.

Eligibity criteria for BCA course: A student must have scored a minimum of 65% marks from a recognized board of india.

Thank you and good luck:)
