Can a school cop stop you for just changing parking stops in school campus'?

It is a crime to be a teenager. A cop will stop you just to see if you can stand his bad manners. There is a reason why schools don't teach civics any more: they want you helpless. Do not fall for that trap. Take a civics course at the local college. If possible, escape from high school and take all your classes at the college. I mean all the classes you think you need. I suggest you take some acting classes and concentrate on vocal skills such as story telling. That alone will boost your earning power more than any other detail. Take a personal financial management course, ECON 101, and get a copy of "Dress For Success" by John Molloy and consider all his advice for students. No school adviser will give you any such advice. They won't even tell you how to do well in their school.
