Go with EK audio osmosis at <a href="http://www.bamm.com." target="_blank">www.bamm.com.</a> It's much better in that you're not gonna get bored with relearning old basic sciences. Overall, I thought CD were great, but then again that's my own bias opinion.
Thanks guys for the responses. I think I'm leaning towards ExamKracker's Audio Osmosis. Does anyone have these that they would like to sell AT THIS MOMENT?...Bamm.com sells them for 150, no shipping costs (thanks Sm00th).
Also, anyone else that have or has been using ExamKrackers please post your comments. Thanks!!
