hi, i wouldn’t worry too much about what gcse subjects you pick, take it from a year 13 who has just finished sixth form! i would just pick the ones that interest you the most as you’ll be doing lots of revision and research into them over the next couple of years. My gcses didn’t really effect what subjects i picked in sixth form, as long as english & maths were of a high grade. Maybe look into picking a language for example french or spanish?
