I've probably overdone it on the practice tests, but we took the academic Scorebuilders through school, I took all six exams offered by both Scorebuilders and O'Sullivan, bought the Online Advantage tests, and the PEAT tests. I have the retired PEAT left, but I really feel like taking the tests has helped me keep a continual benchmark of where my weaknesses are. I took them basically in the order that I listed them, except I alternated Scorebuilders and O'Sullivan. My scores have been:
Academic version: 73.5%; Scorebuilders: 65%, 69%, and 77%; O'Sullivan: 69.5%, 71%, and 74.5%; Online Advantage: 83% and 80%; and PEAT practice exam: 79.5% last weekend. I guess we'll see how I do on the real thing. It's all a mind game at this point.
