GMAT Strategy

hi! everyone
i am currently preparing the GMAT. now,I have gone through the official guide 11th and find that the mathematics is really a piece of cake for me; the Verbal part ,however,is not that easy but not as difficult as what I imagined, i can correctly answer 70% of the questions on average(a bit higer in CR, lower in SC). but I do not take any of other Materials such as the kaplan. since I kown nothing about the real test condition hence feeling nervous these days, I want to know whether the questions represented in the OG is as difficult as,or less difficult than, those in the real test. and if not, do I need to purchase a second book which is more commensurate with the real test? and which one is prefered?

hoping for someone experienced to give me some suggestions. Thanks in advance!!!

The OG will be the most similar to the real thing, but the real test is harder. I would say that my hardest CR and RC questions were about as difficult as some of the LSAT material I used. The math was harder than the OG, mainly because of the layers they throw on. Stacey just wrote a good article yesterday, about this very subject, so try to search for it. If math is easy for you, if you were to take a class, I would recommend Veritas Prep. I took their class, and they helped me a lot with verbal. Verbal was my weakness as well. If you can't afford a class, I would recommend you buy the PowerScore Critical Reasoning Bible and the Manhattan GMAT Sentence Correction guide. Those two were helpful as well. Good luck.

wow, thanks a lot, it seems that I still have plenty of work to do, I will firstly view some LSAT materials(challenge the most difficult GMAT questions ) so I can re-estimate my level and choose whether I should take additional classes.
