It depends on the examination board as well and of course the topics you do. I didn't take GCSE History and for some reason thought that doing it at A-level would be a good idea haha... I do find it interesting but I wasn't used to writing essays, especially source-based ones, so it was a bit of a challenge at first but I got a B overall at AS. I'm gonna retake Unit 2 of my exam (I do Edexcel) coz the sources they gave us were an absolute piss take, and hopefully that will pull me up to an A coz I wasn't that far off. But yeah..... Sorry this probably isn't useful. History is ok, quite interesting and universities value it for its difficulty. If you like it enough to do 2 years of it then you'll be okay.
