Hello,
Gmat700Knight, and welcome to the community. I have it on good authority--from an anonymous
Manhattan Prep instructor--that the newer, condensed version of the old Verbal guides is just as good as its predecessors, that little has changed from one edition to the other. Thus, I would recommend purchasing whichever option cost less. I will say that among students whose debriefs I have read who have used both
Manhattan Prep and PowerScore for CR, many of them have found the second guide to overlap a lot with the first, so one or the other seems to be the general consensus. (If it helps, I have also read that people who are not native English speakers might find the PowerScore CR Bible a little more helpful, though I cannot attest to the statement personally.)
Good luck with your studies. I suspect that with a little expert advice and a disciplined approach, you will reach into the 40s in no time.
