I wonder if you would mind helping me study for my GMAT? I need to score well to enter a graduate program at Doe University, but am having difficulty completing the math problems that require more than simple algebra.
Because you recently graduated with a degree in mathematics, you are naturally the most qualified person for me to turn to. I promise not to monopolize your time--just enough to help me remember some of the calculus that I have forgotten over the years.
I will really appreciate any help you can offer me and will be happy to return the favor when the opportunity arises.
