Hello there

The simple answer for this question is that it totally depends upon the university into which you are interested to take admission for the course of Bachelor in science.

Some of the universities allow admission on the basis of entrance level which is of the university level of itself only and if you qualified it then you can take admission there. And some will gave you direct admission only if you have completed the common eligibility criteria which basically if you've completed your class 10+2 with science stream and minimum gets 50-55%(varies with college to college).

So it will be very easy to find out the process if you will specify the university name.

Best of luck!

Thank you!
