100% triple science, its a lot to know but can really benefit you and i think its great because i did triple but didn't want to do science a level and now i do! but if i dropped it for double i wouldn't be able to be in this position!
If you're academic i would definitely also choose Geography and History as those would be able to give you a vary varied "high brow" gcse results. It may be quite challenging with the revision load but it looks better when applying to sixth forms!
If you get the choice, dont take Japanese lol i took it and its killing me rn
