I think this is similar to the GAMSAT (I sat it in Australia) isn’t it? I would say the best thing you can do is to put yourself under the same pressure as much as possible. The questions themselves aren’t that difficult I don’t think, it’s the sheer volume of them. Especially the comprehension stuff if you aren’t in a profession already where you do a lot of reading (I’m not really).
As a guide I did very well in the GAMSAT (scored > 87% of other sitters) I reckon and I’d say you have to do the practice exams to find your weaknesses then drill on them. I found the science easy and the comprehension and essay writing very hard to do in the allotted time (though again, not technically difficult) so I just wrote lots of essays and read way more with a timer on.
I think that’s the only advice I can give. With 6 weeks I’d be spending a day to simulate an exam, then work out where you did well, where you did bad and concentrate on the bad. Revisit this process again about 2 weeks out… and your done.
Whatever you do don’t try and cram the day before, and try to chillax on the day. If it’s anything like when I did it, people will be even madly studying between the tests (we have 3hr morning, 3hr arvo) … as if it’ll make that much difference besides making you go crazy.
