If your answer is never, take the opportunity this week to visit at least one of your professors during their office hours. Most semesters, only a handful of students use this as an opportunity to get to know their professors (they're real people just like you!). As a result, students lose out on one of the biggest resources they have for success in class. Who knows, perhaps you will gain an advisor, a mentor or develop a connection strong enough to get the recommendation letter you may need.
