My brother did UMAT last year without any prep and got a low score. This year we did UMAT together and we did a prep course where we got a set of books to study from. I thought that section 3 book was very similar to the UMAT, both of us got high marks in that section. Section 1 and 2 was pretty good, but those two section are very hard to study for and requires a lot of dedication. If you want the books I can sell them to you as we no longer need them, pretty sure we will get the interview offer. Best of luck!
