I've seen ScoreTop mentioned quite a bit... I've also looked at their website... from what I gather, they put together tests(?) that are supposed to resemble the real thing... Can someone with ScoreTop experience (who doesn't work for them) comment on this source? Is it worth getting? If so, what package do you recommend? Also, how does the material compare to MGMAT questions and CATs?

Also, does anyone know where I can get my hands on some free CATs? I already know about the free CAT that Kaplan and PR give... just wondering if there's others out there....

We also let people take one free CAT. I haven't used Scoretop's materials myself, but my students have told me they haven't been particularly impressed with the stuff. But, again, haven't really looked at it myself.
