After the first day of classes, you may feel that UT is a large school with cold and hard professors. As time passes, however, you will learn that they are human and want you to learn the material and develop as a student. Most professors really do want you to visit them during office hours, so don't be afraid to ask for extra help!
Some professors may be difficult to understand, but you will be surprised how easily you pick up on their lingual nuances. Teaching assistants will often make you laugh with clever explanations and witty responses to questions. You will encounter a bad seed from time-to-time, though. Whether it is a professor who is too wrapped up in his research, impossible to understand, or generally lousy at lecturing, chances are strong that you will have no choice but to endure a few bad profs. Every professor has quirks and pet peeves, such as late students, absent students, cell phones, lack of class participation, sleeping, or the mandatory squirming and packing up by students around the class's ending time. Tennessee 101 is a useful tool to check out professors while scheduling classes. Remember, however, that evaluations are completed by the students that actually show up to class. The expected grades they report and the professor evaluation may be higher than if all students were present.
