Well, Ive just finished 2nd year at glasgow so no clinical stuff yet but theres been basically no chemistry. The stuff there has been has been the overlapping aspect with biology (e.g. protein structure), but theres also biotech things (my friend said she learnt PCR in her highers..). But apart from that, not really.
The course is mainly Alevel biology but 1000x more complicated and hard! I mean, like adding to the relatively 'simple' stuff at A level, making you realise its much more complex than you'd ever thought before.
