I think a lot of people who are serious about getting into medicine use medentry as they are very well known and have permeated the community through word of mouth. Whether they actually live up to their reputation of being ‘number one for UMAT/Interview training’ depends entirely on who you talk to. The only thing I know for sure is that there are people who will do well in the UMAT without any preparation whatsoever, and that there are people who will do poorly in the UMAT even with extensive preparation. Obviously to maximise your chances of improving your base UMAT skill, you have to prepare, but this usually comes at significant financial cost.
Last year I did the medentry UMAT two day course which also came with the online package, and I honestly wouldn’t recommend doing the lectures. They wasted two days in the holidays, which is a lot of time in year 12, and mostly just rushed through content available on the LMS. I also didn’t properly utilise the online resources, however I do think that if you are proactive and organised you can get your money’s worth out of the distance package by doing all the drills and practice exams, treating the UMAT as another one of your subjects.
