Hello!
First of all, I am new to this forum so please alert me of any mistakes I may make!
@Freshlord,
My personal advice to you is only based on my own experience and the experiences of some of my friends. When I did Medentry, similar to yourself, my results were appalling and I agree, completely depressing too. The most important thing to realize that you have a lot of time to improve be that through Medentry or of your own volition. It is vital not to lose confidence as the UMAT is a test in which the state of your mind plays a massive role.
If it is any consolation, when I did a Medentry practice exam on the workshop day my results placed me around the 40%ile, this was after quite a bit of practice too! However in the actual UMAT I did much better than this and it just goes to show that being disheartened is not the way to go. Just take any result you get given with a pinch of salt.
Good Luck,
Chop.
