Probably did these ages ago, but never mind.
1) Chem, maths, physics.
2) AAA. I'd like to get an A*, but I don't need it for the uni I'm planning on firming, so not gonna stress about it.
3) Don't want to specify uni, but to study physics.
4) ?????
5) Probably not, I'd try to get an engineering apprenticeship or go through clearing (depends what you mean by failing though).
6) Idk, I really like languages.
7) Cba, but doing OCR Chem A (resitting F322), AQA Physics A, and OCR Maths (not MEI though).
