Hello,

Admission into BSc is given on the basis of merit. Process is :-

Major Eligibility criteria :- candidate must have passed 12th from a recognized board. There might be some cutoff for biology which will vary as per college.

College authority prepares the percentage cutoff every year. For top college/universities have cutoff like 75%-85% even ranging upto 90% if it is highly demanded and seat matrix is less.

same goes for private institutes but they have lower percentage bar. It is hard to get government college for BSc with 55%. You have to choose private institute.  Not to worry there are good private campus who does best for students so that they will know more about what they are capable of and put more focus in it. They even provide platform to students so that they will get to know and prepare for market world.  in Addition, fee is also okay.

Hope it helps!
