Hello all! Ok so I'm scheduled to take the GMAT in about 5 weeks. I have purchased the Manhattan math and sentence correction guide and the Princeton Review 1,012 questions book. Do you all think I need the newest official guide? I have the older version but it is about 75% complete from studying previously. I am not sure about buying it as I don't think I will have time for it, what do you guys think? What has worked best for you?
