In term 2, I would try to switch Envir Sci 1A03 to C01 once you switch your Envir Sci 1A03 lab to a different time. I would also switch your Bio 1A03 tutorial (and I think you have to switch your Bio 1A03 lab as well) to T/L 45, 46, 47 or 48. This will allow you to finish at 1:20 on Tuesday, Wednesday and Friday instead of 4:20. It also gives you an ealier bio tutorial time but same lab time.
For term 1, I would switch Bio 1M03 to C04 instead of C03. I would also switch your Bio 1M03 lab/tutorial to T/L 1, 2, 3, or 4. This will substantially make your days end earlier. Instead of finishing at 5:30 and 6:30 every day except for Friday, the lastest you would end is 2:30 on Tuesday, 1:30 on Monday, 1:30 on Thursday, and 4:30 on Wednesday.
How does that sound?
