as a new student i started flying before i started ground school. thats ok but i wish i would have taken the ground school first, at least this class, signs marking and procedures. taxing to to and from the runway is kind of crazy at a small airport and totally overwhelming at a large one. if you are going to start flying do yourself a big favor and take the course of signs marking and procedures. you will be happy you did.
