Try Manhattan GMAT's practice exams. I found the questions to be very tough, especially given the time constraints. Even if you don't time yourself, they're still quite tough. Quite unnecessarily tough, IMHO. Their scoring algorithm truly gives you a tougher question for each tough question you answer correctly.

(This comes from someone who scored perfect in quant on the real test.)
