Study, study, study! Mizzou's reputation is that of a party school, but the academics side is very difficult. The workload varies by professor, but be prepared to study long hours and spend lots of time on homework. For the most part, the professors are knowledgeable and helpful. Professors have designated office hours, but they will make exceptions for students who cannot attend them. They are always willing to talk to students about grades and classes. The workload can sometimes be overwhelming, but one thing to remember is to keep a cool head about it and take one thing at a time.
The weakness of the academics is that there are classes that hold almost 300 students. This makes it a little impersonal, but professors are really good about talking to students one on one if need be. Advisers are useful tools during students' four years at school. They are very helpful when it comes to finding classes and working out the perfect schedule. With a little information about you, they can suggest classes that you might want to take. At the end of every semester, students need to make an appointment to see an adviser, so that they can get their schedules for the following semester all worked out.
