Help choosing first year elective?

(Original post by blue.stripes)
So I'm going to be doing Physics 1 (Semester One), Maths 1R (Semester One) and Maths 1S (Semester 2). I'd like to do something with a smaller work load and more enjoyable for Semester 1, then maybe take on something a bit heavier for semester 2? I'm considering a career in Medicine or Medical Physics, so I want a really great transcript.

Here's my options:

-Biology (1A) (S1)
-Biology (1B) (S2)
-Introduction to Finance, Investment and Institution (S1)
-Introductory Economics (S2)
-Communism and its Collapse (S2)
-Theological and Religious Studies
-Introduction to Business Report and Financial Accounting (S2)
-Psychology 1A (S1)
-Psychology 1B (S2)

I have A (English), A (Maths), A (History), A (Modern Studies), A (Physics), B (Chemistry) and B (Human Biology) in Scottish Highers. I think I'd meet the entry requirements for all of my options.

Thanks!
