I wouldn't really recommend taking
both Graphics and Art. I took Photography and Art at A Level and just feel like I totally wasted one potentially useful A Level (although Graphics might actually be alright - most people know that Photography is a doss
). But if you do find you're becoming more interested in an Art/design career towards the end of your A Levels you can always go and do a Foundation course in Art and Design, which gives you a good all round footing for going on to different ~pathways~ and is pretty open. For that, I'd suggest to take Fine art instead of Graphics, but I'm probably biased
Really, all I'm saying here, is that unless you're totally sure you're going to go on to do something artsy at University/in later life, then there's not too much point taking two potentially very similar subjects.
Furthermore, I found out this year whilst applying, there are a few universities who don't accept more than one vocational subject at a level if you're applying to an academic course.
I hate to seem like I'm putting a downer on the whole thing, but really, art/design universities don't care too much if you have two vocational A Levels or one. Hope I haven't unnecessarily confused things either :P
