Yes, I'm practising for my GRE's. I'm not really worried about the analytic writing though, philosophy students are basically trained exclusively on that stuff.
Chimera of Filth
A gruesome beast with dripping flesh
Clings to me as a sick fixture
My throbbing heart it gnawed apart
It stalks and hunts me through mirrors
This website had taken the entire pool of GRE Analytical Writing topics, removed all duplicate topics, and sorted them by how likely they are to appear on your test. Check it out. It's pretty helpful.
Now that I've already taken the GRE, they add something which would have been the easiest section of all for me. Great timing.
