FSU offers both online and on-campus classes (for both undergraduates and graduates) during semesters and over the summer and winter breaks. Online classes are good for commuting students. If you do not want to come to campus every day, then take an online class. It makes things a lot easier. Also, the online classes over the summer and winter break are a good way to catch up or keep ahead of your class requirements. Other than online classes, in regular courses, the professors may start out the semester as stuck-up, but near the middle, they begin to lighten up. The professors teach a variety of classes within a subject, so you should expect to take every teacher in your major at least once. When it comes time to graduate, you will know the teachers in your department so well that any of them should be able to write you a strong recommendation for graduate school, if you decide to pursue that option.
A student is not allowed to take more than 17.5 credits, unless he or she has approval from an academic adviser, the person who will unlock your account to register for classes the following semester. You can either personally choose or be randomly assigned to an adviser for your remaining college career. This is a professor in your major who will be your mentor and, in a sense, guidance counselor. They are there if you need to talk about classes or anything else. The best advice is to choose one yourself because then you know you will have an adviser whom you can talk to comfortably.
