I have a question from Prep-Course Book (insert name of some outside prep course book, lesson, or lecture) XYZ. Can you explain the answer to me?
Please limit your questions to the GMAT Score curriculum and to the GMAT Score course material. In many cases, if the question can be quickly answered by reviewing the appropriate sections, we will ask you to do so. If you are requesting a definition of a common English word, we may ask you to consult a dictionary. If you are looking to understand to basic mathematical principles, we may ask you to consult some standard math references or math resources on the Internet.
