First, I want to thank you for this website. I think it is a powerful tool to help you prepare for the GMAT. However, there is one problem. When I try to got hrough the problems listed in the Math section on this site it looks like Greek to me. You should see some of the problems posted. I dont know how anyone can follwo these problems. They are obviously written in short-hand but they are extremely difficult to follow. Can you porvide some sort of reference for the short-hand used to explain the DS and PS problems.
any specific posts that you want to talk about? if you dont understand, you can reply to the post and seek a clarification.
