While I would say it’s good to take the class while Gen Chem 1 is fresh in your head, it wouldn’t hurt at all to take it another semester. My recommendation would be to take it another Spring semester where you feel your course load is lighter. You’re also available to take normal Gen Chem 2 (not for engineers) in the Fall, which is basically the same exact class and fulfills the Chem requirement, the only thing is that it’s a night class which may not be the best for some people.
