How to determine biology acceptance rates?

Hi! I wanted to find out… is there any way to determine the biology major acceptance rates for undergraduate school? For example, what is the acceptance rate of the biology major of Johns Hopkins, UCLA, Northwestern, UC Berkeley, Columbia, etc?

Nope, the acceptance rates are general, except in cases where the university is broken down into colleges (Arts & Sciences, Engineering, etc). The major you put on your application is not going to be your declared major until you actually declare it after matriculation.
