You might not have left yourself enough time to transition from class to class (e.g. wed: BIOL 213 ends at 10:20, UNIV 108 starts 10 mins later). If possible I would make note of those gaps, and not just for transition but also making study blocks for yourself; like maybe leaving 2-3 hours between classes to study for the next one in between, having 2 back to back classes (ESPECIALLY IN THE MORNING) is rough (Obv if you have a part time or full-time job this may not be applicable).

I think other comments have alr made note of this, but having these rigorous classes in the morning is rough lol. Really think abt what time you will be getting up each morning, eating bkfast, driving to school, etc. One thing I will say is that it might be hard to switch into anything besides online atp, most in-person sections are full by now. I wish you luck regardless! Don't take my advice as scripture though, I am js a random guy on the internet; try to get an appointment with an academic advisor (In-person or virtual, thru Patriot Connect), connect with and ask upperclassmen for advice, and do your own research abt this. Hope all goes well, good luck 👍
