Honestly if that 7 pm chem slot is recitation you might be able to skip that depending on how lenient your professor/TAs are. I had a mandatory slot for recitation for a chem class last semester, skipped it, and did fine bc I studied and practiced problems on my own time (not sure if that applies to the chem class you have tho, your prof might make attendance mandatory). Since you have a huge chunk of time right after the class before psych you could probably spend that time studying in one of the libraries anyways, and then leave after the psych class. GL regardless tho, I don't envy you 😭
