Generally, any student regardless of his study background can get into a BCA course.Some colleges do segregate according to maths and non-maths students, as some colleges do give admissions to the students having maths as a class 12th subject. But being a science biology student won't make a difference, at least in the admission process. Keeping in mind that you have a science bio background and BCA is a computer oriented course, you will or might face some problems that the students of commerce/computer and science/CS students do not face.
Having prior knowledge of computer is an advantage for the CS students, as the first month of college will be very easy for them. But for a non-computer background, it is important to regularly cover up the topics. Also, one has to keep interest in computer technologies and updates.
So, ultimately anyone can do a BCA course. You just have to be regular in the starting as it will be new for you.
