How hard is it to enroll in upper div bio classes as a psych major at CSUEB?

I love biology and want to take high level biology classes to fulfill some sick need inside of me. However, I already have a bachelors from a previous school and the biology department doesnt take 2nd bachelor seekers. It seems like i’ll be attending either as a pscyh or chem (BA) major.

I’m just wondering how hard it is to sign up for upper div bio classes when I’m not a biology major? Any feedback would be greatly appreciated!

Perhaps use An error has occurred. to check whether the courses of interest in recent past semesters have been completely full.
