I'm currently getting straight 9s in 11 GCSEs (I'm in Year 10 so this could change, though hopefully not) and I'll list my extra-curricular. I'm concerned about whether I'm doing enough or not because I had my career interview with my school and they said I'm doing as much as I can clearly so Harvard (+ some other schools) could well be an option, so at least my application would be good.
Basically, I play volleyball local-league level and am hoping to do regional and maybe even national in the next 2-3 years. I volunteer weekly at a charity, I do ballet weekly, and I have been part of a religious and ethnic community where I have done community work regularly for the past 10 years, and I do Rangers.
I'm currently working on a local maths competition result, but I'm also waiting on a national language competition's result as well and we'll see how that goes. I plan on participating in the SMC in future years and the BPhO too hopefully. I'm getting in some work experience in research soon and hope to in upcoming holidays. I'm also planning on applying to PROMYS Europe next year and right now at least, I'm starting to study for the ACT as I'm taking it in Year 11, rather than Year 12, as I'll be quite busy with schoolwork+ecs then so it seems better as GCSEs are pretty lightwork anyway.
For A-levels, I was talking to my advisor and she said I could take 5 A-levels though whether the school will allow me depends on how well they think I could cope. Though it's likely they'll let me at least try and I'm free to drop the subject if it becomes too much, though I don't want my lack of an A-level to be the reason I'm not as good as other applicants.
Anyway, if anyone has advice or feedback it would be very much appreciated
