I already have all the examkrackers material (audio osmosis, examkrackers review set, 1001s and 101s, etc) so is it worth signing up for the live MCAT class? It says the lectures are only 50 minutes and the rest of the time is spent on testing...so its not worth paying $1000+ just to sit there and work on the practice materials when I can do that at home right? or are the materials different? even then is it worth it?
