My advice would be to not emphasise or do too many of the riddle questions (eg. If Carl goes on the bus monday and thursday, but Ben doesn't go on wednesday, and Darren goes on the bus with Annabel, on which day does blah blah blah etc). These did NOT appear on the UMAT last year (and apparently appeared only infrequently other years). Section 1 seems to be far more science/experiment-centric, and some of the questions are VERY similar to the maths/science ones on the GAT. Having said that, the test could be completely different this year to previous years...
Whelp time to do a few LSAT & GAT questions

. I think then that 2 sections of LSAT is beneficial for Logical reasoning (5 Options and all answers are close), and yeah I'm gonna have a shot at some GAT past papers.
Looking at GAT and feeling sympathy for Victorians, looks a bit harder than QCS, but our QCS is sorta the basis of our ATAR equivalent (based on how well the school does).
By the way, is Medentry's S1 in anyway similar to the actual UMAT? I heard that S2 is basically different.

Even their Section 3 is apparently a bit different?
