It sounds to me like you probably need to work on your fundamentals. Your speed will improve considerably if you memorize basic calculations like squares and cubes of common numbers on the GMAT. There a number of resources out there for studying number properties,
MGMAT's book is good, but I really liked Kaplan Math Workbook for covering all of the fundamentals.
