thanks for the feedback. i admit that i too felt the questions were pretty good.
i did as well as i do on other tests, but was initially thrown off by the calculations involved. normally i'm looking for a concept that they're testing, an approach which works for most of the difficult questions. here, i found that some questions simply required the 3-digit X 3-digit multiplication.
any idea if these guys sell just a Quant Question bank? how would yuu compare them to the challenges (i still have a lot of challenges left to practice).
as for the clock, i found it a little irritating...i believe in practice material that pushes you a little harder than the real thing
