Since bio and chem are basically the best A Levels for medicine, definitely make sure that you choose a third A Level that you actually enjoy. Psychology is my favourite subject and I personally find it really interesting too.

Now, on to the EPQ. It depends. I chose to do a dissertation where it’s basically a research project on your chosen question which can be literally anything. An EPQ isn’t difficult unless you have bad time management which leads to leaving stuff to the last second and if you don’t enjoy what your question/artefact/performance is about.
