Thanks guys. I ended up choosing Earth Sc 1G03 because it's a prerequiste for gemstones in second year, which seems like an interesting course. I also chose English 1A03 just to see if it's something I may want to consider doing in the future since I'm not dead set on science.
For second year, I looked up requirements for psychology/neuroscience and life sci honors and it said both chems and both psychs so I'm doing that. The only thing I'm missing is physics 1B03 but that can be completed in second year, which I think I'll do rather than having a huge physics load in first year since I'm terrible at it.
