Thanks
I wish I could help you, but first, I don't have the Quant section of [tooltip=Official Guide]OG[/tooltip] in soft copy format. (I think that every GMAT taker should have the [tooltip=Official Guide]OG[/tooltip]. If you don't have it, you should buy one or borrow it from a friend) second, eventhough I have some useful materials, I don't know how to upload them. If interested, please tell me how, and I will upload them as soon as possible.
Cheers.
