Self-studying Biology and Chemistry

Hello all,

I'm wanting to self-study GCSEs and A-Levels in both Biology and Chemistry. However, I see both subjects have a practical component at both GCSE Level and Advanced Level. How would I sit the practical component? Could I bypass it by taking the international GCSEs and A-Levels?

Normally you find someone who offers the practical component as a course. It costs money. The unis will say whether they want the practical endorsement or not.

Yeah, all the medical schools I sent letters to want the practical endorsement. I'm on good terms with the teachers at my secondary school so they might let me do the practical endorsement there.
I'm gonna use my summer vacation to begin learning A-Level Biology and Chemistry. Gonna start with the AS level things first, do you know the name of the textbook the schools use? I looked on amazon but they only show student guides/revision guides.
