ok so could someone explain prep-op to me? my state does not have prep op and a see some girls only doing lv5 skills and some doing fulls on floor. to me thats like cheating doing lv5 skills in a lv7 routine? anyone else feel this way? what im relly looking for is an explanation of what it is and how it works and the requirements. i really dont get it. and y do some states have it and not others?
