Olly, I did similar a couple of yrs ago:
L3 Chemistry
L3 Biology
L3 English
L3 Physics
L3 Statistics
L3 History
L3 Geography
+ Scholarship in Bio, stats, english, physics and history.
I didn't study, and did pretty well, mostly E's and a few M's.
In saying that, I don't recommend the not studying route to others - if you go to uni you can't really get away not studying - in Law at least.
