fellow medic here, my biggest advice is to get off tsr. these people are the top candidates who feel the need to show off most of the time. i guarantee that you will improve over time but that progress will never feel like enough if you are constantly comparing yourself to people that are on here. in my experience, i got 2400 the day before my ucat and ended up getting 3000+ on the actual day- it's all the luck of the draw. prioritise your mental health in this application cycle- it's your most important asset.
