i'm not sure, i mean you will probably have a higher cognitive and logical ability to rationally answer the questions. But that doesn't necessarily mean you will succeed, as ACER says you can't study for the UMAT, but preparation by purchasing the question booklets and doing IQ puzzles and crap will help alot. But anyway you are only in YR 10 and you shouldn't be worrying about UMAT right now, you have two years to enjoy the wonders of the HSC *cough*, how about wait till the start of 2011, you will have about 6 months to prepare which is plenty of time to prepare for the test. Hope this helps.
