completely agree - as long as they're subjects you enjoy you and you feel confident with them at the moment they will be great options for you. My school gave the option of choosing geography and/or history and/or a language - heavily encouraging a language but not making it compulsory. I chose to geography and spanish + 2 other options. I know of people who have chosen both geog and history and find that the work load is very high, particularly from history. This may, however, be because most of the history department left during the 3 year course leaving multiple classes without teachers for a prolonged period of time (my school is supposed to have 7 history teachers, it is not because the school is at all small lol). History stidents mostly find that there is extensive amounts to learn and revise; however, as i say, this may be because they were left to 'fend for themselves' due to the lack of proper teaching. If you feel happy with the options you are choosing and get on well with the respective departments though, I'm sure you'll do great!
