Order all the New set of
Manhattan Gmat book strategies, email them at student
[email protected] they will send you all the tools you need. Take an online course as well from
Manhattan GMAT, but before you commit to the online version class, review all the material's & concept and do all the problems that are asked for in the syllabi from
manhattan gmat, the material is extremely heavy for anyone, and to get the most bang for your buck, is to give yourself at least 2 months to review all the material, spend around 1 week per book, do the assigned homework, and then take the class to reaffirm your learning & concepts, get to know their website along with the gmatclub.com website, learn to ask questions in this forum, gmatclub.com, it's extremely important for you to learn to use this site, everyone here seems to have one goal in mind, to earn a high score on this dreadful-age old exam, and a natural collaboration seems to exist here. Oh, and yeah, drop everything else in your life for 3-6 months until you're done.
If you want the most practice, order the old OG Guides, and practice, practice, practice. I hear that the GMATCLUB.com exam's are pretty good too, I haven't tried them yet, i'll be using the CAT exam's in the next 2 weeks, but I have read a number of positive remarks about them.
