Hi all
I just took the Gmat exam a week ago and I got 520(Q47,V16)

.I have read the Official Gmat 12th edition and 2thED of verbal,I studied all
manhattan books and my weak points are RC,SC and lack of concentration in verbal questions on the exam day!!(AND I am not native!)I want to retake the exam but I don't know what to read this time!I also used Gmatpill RC and Grockit videos.There are several resources but I don't know which one would work for me such as : GMATPILL RC,Aristotle RC1&2 for RC , e-gmat SC,aristotle SC Grail for SC and Kaplan Verbal books,Veritas Verbal books....I don't want to waste of my time by choosing the wrong material for studing and I have only one month to prepare myself(I left my job so I have a complete full time for studing ).I would appreciate any suggestions.
