Definitely recommend MedEntry if only for the huge amount of Section 3 resources they have on the LMS, and the tricks they teach you at the lecture.
Section 1: Personally didn't need to learn anything for this, got 100% on the first practice Section 1 I did so never bothered again.
Section 2: Really struggled with this at first, MedEntry's Section 2's were quite different to the real thing but I still improved from my practice UMAT mark after doing the MedEntry exams.
Section 3: Initially I had absolutely no idea how to do some of the patterns. The lecture taught me some great techniques and I was able to refine these using the material on the LMS. Eventually you get to the point where nothing is really surprising anymore, there is only so many ways a component can move around a circle....
Ended up getting 100th percentile which I don't think I would ever have achieved without the wealth of material on MedEntry's LMS. I only got through about 4 full practice exams, if anyone completes all of them I don't see how you can't get 100th, but have fun spending 100 hours doing UMAT revision........
