General Chemistry1 is the typical 1st class for would-be Chem&Bio majors AND the one premeds take; premeds cannot take the “lighter” version in this subject.
Universities often offer an Honors version of many premed pre-reqs, that is NOT mandatory; of course a few universities have enough chemistry majors to offer a specific class just for them but it’s rather uncommon. Obviously if the chem majors have their own special sequence, non chem majors premeds don’t take that class.
I’ll check for TAMU.
ETA: at TAMU, the first year sequence for Biology and Chemistry majors is the same.
The difference is in the Math sequence (Calculus for Biology majors vs. Calculus).
On the other hand, there’s typically a calculus-based Physics class for Physics and Engineering majors, different from the Algebra-based Physics class for Biology and (generally) chemistry majors. Some universities (such as WashU) can require the calculus-based class but most universities don’t.
Ultimately it’s not the most important part of the post.
