I do all three of these, and chose History and Triple Science. Triple Science I didn't really have a choice after my exam results on Thursday but I'm glad I'm doing it. History is interesting in most cases - some things are dull, as with every subject, but overall I think it's great. Geography is good as well, and I like it more than Triple Science most of the time and it's (hopefully) an A* that's not that hard to get come the exams, but because it's straightforward I sometimes lose a little bit of interest.
