I have looked at a past paper. Sorry my question was too vague. I know the umat consists of 3 parts the IQ reasoning part, understanding people and an englishy problem-solving part (sort of like Australian math comp logic questions 5-9). What I meant in saying how it works was concerned with how the marks were added and the people given their percentiles. Acer is pretty evasive about its marking scheme (??).
Plus, I am considering to do Medentry as prep. Now, I myself am against the very notion of such courses (whatever they can be classified as), UMAT is meant to seek people with ability not just whose parents can shell out copious amounts off money for their purposes. But, I really want to get into med in general (and neurosurgery to be particular), and I don't want to risk it (from my research, a common dilemma for people in a similar situation).
Ok, plus I more thing. I proposed this to my parents a while back (year ~10ish, actually last year) after doing the brain bee challenge thing, I more like nagged them about it. But, now they are really committed to letting me have the money to do it. Pretty much everyone I talked to said they did medentry. Thanks for the responses. A quick reply would be nice, I am deciding today...
