@ mavisgibbons. I'll be chasing you up for my $10 when results come out. :p
I'll honestly just be happy to do better than I did on the UMAT, which probably won't happen considering I did no prep.
@mikee65. It didn't seem too bad. The science section was relatively straight forward and doesn't look too hard to get right with practice. It is a shame Melbourne does not double weight this section, because it would make it so much easier for us science kids to get a better score. I would definitely say study the most for chem, as they test it a lot (almost 50% of the section I would say) and some of it is quite difficult, especially the organic pathways and reactions. Other aspects are really easy, like identify E-Z isomers. As for the physics stuff, a VCE textbook should more than suffice. Don't even waste your time studying for biology. It is unfortunately almost 100% graph interpretation, many of which are just made to confuse you. Very little of the biology section requires prior knowledge. That having been said, it seems that they do love testing the cardiac cycle and oxygen binding curves. I also think a genetics question is always on there, but these aren't really that hard.
After having trawled through pagingdr threads, they certainly do seem to recycle some section three questions, apparently the harder and more senseless ones.
Section 2 will be woeful for me as I did no preparation. I managed to complete two very bad essays. The topics were on humour and space exploration.
Section 1 is really hard to judge. There are some questions where I was somewhat confident, and others where I had no idea and just guessed. This section is a little similar to UMAT, but it has a heavy focus on the humanities. There was stuff on there about politics, history, music, poetry, psychology, cartoon analysis. It is all just critical reading for the most part. There was also a whack problem solving question on there, and again, you are bombarded with many words you have never heard of before in your life.
It was definitely worth the money, but annoyed that I had to miss a day of uni for it. Will be interesting to see how I did...
If you want to see specifically what type of questions are on GAMSAT, then check out the ACER books (links are floating around here somewhere) and also the debrief threads on pagingdr give lots of info about what concepts specific questions were testing.
