Advice that was givin to me that's worked pretty well. Make a list of all the questions you would want to know the answeres to. Then go to the schools web site and research them. Most questions can be answered this way. Then make a list of the questions you couldn't find answers to and ask those. For example do they super score the ACT or do they prefer the ACT or SAT. I can never seem to find those on the web site so those have to be asked.
