I'd advise you to search through the forums and look for suggestions on books. Though there are books like Cracking Verbal by Princeton Review which covers all the different areas on the Verbal section,but that is good if you're targetting between 500-600. If you're looking for scores beyond that ,you may wanna get books which target each specific area such as SC, CR and RC and the various topics in Maths. I am using Manhattan Math Strategy Guides for tackling the Quant section and think they are really good. For Verbal, I think Manhattan SC Guide and Aristotle SC Grail would suffice .Both books will help you tackle SC questions properly. For CR , you may wanna go for Powescore CR Bible or MGMAT CR Guide. I have both and I find CR Bible to a better option. Though I haven't started with RC yet as I am quite tied up with SC and CR in Verbal,but I plan to go through MGMAT RC Guide for strategies and OG12 RC passages and RC99 for practise .
