Favourite: Physics | I liked how very little of it was just pure memory - it involved a lot of problem solving. Almost the same for Chemistry, and Chemistry would've been my favourite if I didn't have to remember loads of pointless colours.
Least favourite: Computer Science | ******** subject. Gonna drop it next year. Lots of memory, lots of problem solving, and then a few essay questions on top of that. A subject should have no more than two of those.
(Both of these are AS btw, only just finished year 12)
