Is psychology a level along 3 science a levels acceptable for medical universitiesWatch
Entry requirements vary across universities. However, speaking for Sheffield, our MBChB Medicine degree course accepts any combination of two sciences alongside another A level, so long as one is Chemistry or Biology. Psychology is considered as one of these, but in your case you have both Chem/Bio so you would be fine to apply! The University also requires a minimum score of 2420/3600 in the UCAT for an application to be considered, so this is worth thinking about as well.

The British Medical Association also has a guide on applying to study medicine, which can be found here:
I hope this helps and best of luck with your A levels!
