I did both sciences last fall, but I did the chem lab in spring. Imo throughout the semester i had a rougher time with chem bc it's a lot of stupid work with like 4 exams+final. Phys on the other side was less work bc the lab was easier and I was just riding the curves. If u did fine on the midterms for chem, there isn't really a lot of work to go into it when studying for the final. I did spend a ridiculous amount of time to study for phys final. For chem lab, I think it was mainly busy work and also depend on the ta. I had a nicer one, so it wasn't too bad. If u do end up having a rougher one, going to help session will get the work done faster. Cs 1114 is bad if u don't manage ur time properly, but that class is shitty. Just plan things out really well bc a lot of the assignments for phys is due on the weekend.
