Hi there! I currently started preparing GMAT. I've done some research and I'm kind of struggling in deciding which books to buy. I bought the Official Guide and I think I will finish all the exercises by the end of next week. My aim is 700+, I'm working full-time on GMAT and I've got 4 more weeks left. My plan is to finish the official guide, buy a couple more books to improve the parts in which I feel weaker and then do as much practice tests as I possible. Thus, I've heard that the Manhattan advanced books are pretty useful. But my question is the following: to what extent do they differ from the OG? Are there a lot of different types of questions that I won't find in the OG? Also, according to your experience, is my plan reasonable?
Thanks
Thanks
