Hey Patrick,
I looked at all your possibilites to solve your conflict. One involves switch courses between terms. Another involves switching your entire term two around. However, the chance you will be able to do this now is slim since most of these are probably full. Your best bet, which I think is actually the best option here, is to switch your ECON 1BB3 course to 1E, the evening course. It's 3 hours Wednesday night only once a week. It's better than having your courses all over the place trying to fit the day class in. If it's full, just call the economics undergrad office and let them know you need to get it to solve your conflict.
First Term:
Switch
Physics 1D03 to C01. If that's full, you can try switching it to C02, but for that, you'll have to move engineer 1P03 somewhere else.
You can switch
Math 1Z04 to C02 if you move the physics lab and engineer 1D03 tutorial.
For the last step, switch the
chem lab and physics lab to Tuesday, Wednesday, or Thursday afternoons at 14:30.
Switch the
engineer 1D03 tutorial to Monday.
If you make those changes, all your courses will be earlier, with a nice break before your two labs in the afternoon. Plus you'd get off much earlier on Fridays.
