You can get a feel for how others view the course, assignments, grades, etc. Be sure to check the bulletin boards in your department. Famous people in your field may be lecturing at UT that day. Take advantage of the opportunity. Don't get behind in your studying.
Many professors give comprehensive exams at the end of the semester.
Don't assume, just because one professor grades on a scale of 100, that they all do. If you don't understand an assignment, don't hesitate to contact the professor or teaching assistant. Take advantage of your professor's office hours to get additional help or questions answered. Use your teaching assistants. Ask if you can show them your rough draft for their comments.
