After studying for the quantitative section of the GMAT, you should only need a few days to studying for IR to do well. You only need a day to study for AWA. Just read.
I have two questions to ask.
1) The quantitative part, I do not know anything about math. So starting from zero, I can study it in a couple of months? Or require past knowledge?
Yes, you can; just grab a copy of the MGMAT Math foundation.
2) I have to prepare for the gmat to access an Italian university that asks only the verbal and quantitative. But I want to use the same test, after 2 years of college Italian to enter a master's degree at london business school or INSEAD. But, for the master in these two universities will be a problem if I did only the verbal and quantitative?
You mean skipping IR and AWA? If that's what you mean, then YES. They will have an issue with you skipping those.
thanks for the replies. then advise me to do all parts of the gmat? that is, as I want to do only once in order to use it later for LBS is conviente also do IR and AWA at this time, or should I do next? If I were only verbal and quantitative, would not be valid for the LBS?
But what about in the synthesis of IR and AWA? is difficult to prepare? thanks
