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 offer one free CAT - just go to our store (linked from our home page) to "buy" it.

I'll leave commenting on competitors to students who have actually used their material. :)
