Okay, so I've started looking at GRE stuff (as in, for the New GRE which comes into place this August). I'm sitting it in November this year (about a month after my thesis is due) so then I can apply to graduate schools in January-March 2012 for Admission in September 2012.
I have to say that I prefer the format of the New GRE, it seems to be more about reasoning rather than memorisation (but there is also still a fair bit of that too, for instance, it is likely that I will have to memorise the quadratic formula - now there's a blast from the past!). I'm just frustrated that I have to re-learn VCE Methods (though no calculus) plus some other geometry stuff that I don't remember actually ever learning, in order to enter into a degree programme that will have almost nothing to do with quantitative anything! Though I am suprised at how much I have retained somewhere in my head.
Also, a lack of past materials is a mixed blessing. At least it limits how much preparation I could do for it (at the moment, I'm just looking at quantitative questions once or twice a week. I'll probably start looking more at the verbal in August).
