Anything above a 800 (it's on a 200~900point (the top end changes from year to year, wtf) scale) seems pretty good. It appears that quality singlevolume preparation materials cannot be had at any price. Perhaps one ought be written?
 We took the exam 20091010. I don't see myself updating this page much further. (Dank 02:53, 12 November 2009 (UTC))
