Getting money is a problem for everybody you can print it, steal it, get it from somebody else or earn it. I don't recommend the first to however because they can result in a very long vacation. Find out how much it really costs and see if you can do odd jobs around the neighborhood or if your school job board has something you can do. If nothing else, if you are good in a subject, you might be able to tutor for money. People have been figuring out how to legally get money form somebody else's pocket into theirs for years and you should be able to do the same.
