Ok people, thanks for the advice and opinions, I really appreciate it! The trouble is; there is a new dilemma! It turns out that my choice of subjects at my school sixth form clashed (dammit!), so I was only able to take English Lit, History and Biology at school with Chemistry taken outside of school at Liverpool's Community College. However, I have also been roped into taking Physics, instead of Chemistry, at school (whilst I am actually taking Chemistry at college!). This means I will be doing 6 AS-Levels, in total: English Lit, History, Biology, Chemistry, Physics and General Studies. The latter isn't very hard, or important, I'm told, but the other five don't exactly look easy! Am I taking too much on? Please bare in mind also, that the Chemistry is only on one night per week; in a 3 hour Tuesday evening session.
By the way, the reason I didn't take Gov and Politics etc as an extra, was because I had to take Chemistry as a college extra, and my school does not offer any of the subject mentioned in the thread's title.
