I finally completed signing up for next year's classes. I will be taking:

Organic Chemistry
Science in Context
How the Universe Works
Earth and Life

I decided against doing more Maths next year, seeing that I only passed level 1 Maths this year. Since there are no other pure chemistry classes at level 2 and I only waanted to take one level 3 class for now, I'm taking broader biological and environmental type courses.

I do have two practical requirements to complete so far, for Organic Chemistry and The Molecular World. I will probably take one next summer, the other probably the year after that. This year I didn't feel up to doing a practical block in the UK, but I'll have to next year.
