If possible, here is what I would try to change:
- math 1LT3: possibly try to get into a core at a different time because it's going to be annoying to wait 5 hours between your classes
- the CHEM 1AA3 lab/tutorial on Friday afternoon: I used to have chemistry labs on Friday afternoons, and it sucked! Everyone seems to leave campus early on Fridays, and you're stuck in a chem lab! Maybe try to change it to another afternoon if possible
