Research the Professor

Research the professor as well as the course. Many universities have a lot of flexibility when it comes to electives or when you can take a course. Take the time to find out who is teaching the course before you take it. Ask friends who know the professor and also go to the student union office where they can often give you the information you need. If you are already enrolled in a class with a professor who has a bad reputation, consider dropping the class and retaking it when it is taught by a professor whom you will enjoy.
