Dear Hanu, The GMAX Online or CD course Verbal Sections could be perfect for you. Our students say that the clarity of Abi's approach makes it much easier to score well. The systems she teaches takes most of the guess-work out of solving the questions. The sentence correction section is taught so carefully, it is almost like doing mathematics. Go to the review here to see more about the course.
Dear Little Nemo, There is no overlap between the OG11 and the two review guides. However, the OG10 has most of the OG11 and all of the guides. If you can still find OG10, you may save yourself some money. You should know that there are many OG10 questions not repeated in OG11 and the guides, and many OG11 questions that are new.
Regards to all of you, and good luck with your studies.
Leanna
