I'm seriously considering upgrading to 7 Sage Ultimate in preparation for the 5 December LSAT, but it looks as if the latter half of the curriculum is ALL Prep Test work (which I like), how did you buy all of these prep tests and ensure you got the right versions? Next, some of the material seems like it requires "clean questions" (aka Logic Games), if you're practicing in the alloted space, wouldn't this require having multiple (up to 10!?) copies of the questions?? I know LASC offers the prep-tests, does anyone have a link other than Amazon to be sure we're getting the right ones for this course of study....
