<p>Keep in mind that at this point, with spring semester classes not starting for almost two months, a lot can change. Some senior may realize that he or she absolutely needs that class to graduate, or maybe the professor gets bumped to a smaller classroom because she doesn’t have a full class roster. “Maybe” is infinitely better than “no,” and if you don’t hear back from her, just show up on the first day of class, sit in, and talk to her afterwards… displaying that level of interest will carry you a long ways.</p>
