My friend is thinking of doing a physiotherapy course but he is not sure if he should take chemistry at a further level. He is fine with doing Biology and Physics but just not sure about this one.

What subjects are important to this course at GCSE and A-level??

Thank you!

Erm, well that would depend on the level of understanding that you want to get. Physiotherapy, I would say, would require biology which you say he is already doing. If he then wants to understand the background of the biology, then I would recommend doing chemistry as well. The chemistry will help explain a lot of areas of biolgy where you are normally expected just to accept it.

Biochemistry is the best way to have a fundamental understanding of the mechanics behind biology. You can memorize the citric acid cycle, or you can learn some chemistry knowledge to "re-figure it out" at any point.
