I am new to the forum and hope to crack the exam. I have started with the quantitative portion and i am looking for a single source where i can refresh the theory and practice the questions. I am totally confused with the numerous reviews around about several books on GMAT prep.
i have purchased the Official Guide 13th
Edition (GMAC) and i plan to purchase the quantitative and verbal OG
from GMAC as well. would this be enough to brush up my skills?( i am a little rusty). i read in some blogs that these books would not help to score above 700. Is this true. If so should i also purchase the Manhatten 8 books as well or any other? Please suggest the best.
