Have to watch out though if you have scholarships. Some of them have the equivalent of a self-destruct clause that can be triggered by taking just one semester off. In order to take a NASA internship for one semester, I had to get approval all the way to the top of the chain (president of the university) or I would have permanently lost my tuition scholarship. As it was, although I had administrative approval, when I came back the computer system automatically marked me as a "dropout" and I was blocked out of most log-ins. Took a year to get me reinstated in some of the systems.
