After reading multiple threads, I have gathered this. TPR and TBR - good for a comprehensive review, maybe if you have never seen the material. May slightly be overkill though, probably be presented with more information than necessary. EK - best for a review of the material if you have seen it before or is fresh on your mind. also, the 101 verbal passages is a must. kaplan - had the best practice material. any more information, anyone agree or disagree with anything? also, i just order the EK complete study package, and how many passages and practice is in there?
