<p>Haha are you for real? Chem 1A is a prerequisite for Chem 3A, and Chem 3A is a prequisite for higher chem and Bio 1A, which is a prerequisite for pretty much any upper division bio class. So you could TRY getting into a public health class, though it is usually difficult for non Public Health majors to get in. </p>
<p>Right. But I have to choose from each category. For instance, I can take Chem 1A and Chem 3A but I wouldn’t have to do Bio 1A according to this because there are other options. In this case, X15A/X15.1A & X15.1B/X15.1B…but idk what that means.</p>
