Yes any science (pref physics) and math based subjects will put you in good sted!
Remember to work hard at school and get the best possible results you can! I was often deemed a 'boffin' because I put a lot of time and effort into my GCSE's but it greatly paid off and shut a few people up! As mentioned above, you have the time now to govern what you get on your results day, the harder you work now, the better it pays off for you in future!
Oh, have you had, or are you, taking flying lessons by any chance? If not I would recommend you take a trial lesson in a light aircraft just to see what it's like! Xmas is only round the corner, put that on your list to santa
Best of Luck!
