Fuck this bird course bullshit: what is the theoretical hardest term you could do?

You're limited to a maximum of 5 classes, you're only allowed to do courses that would be allowed for the program/major you pick. Prerequisites must be satisfied, unless it's something that a prof usually overrides

I tried this for the courses open to me, and the hardest term I could come up with was

Pmath 351, Pmath 352, CO255, Math 245, CO330

I didn't do it obviously, cause i'm not fucking dumb, but it got me thinking, what's the hardest combo you could do with any program/major? I feel like it might be something mathphys, because then you could do the pmath + the brutal physics courses, but idk.

As a slightly more reasonable question, what's the hardest term you've personally done? Not hardest individual class, but hardest combination of classes
