<p>Don’t just email the professors. If the semester is about to begin and you still don’t have your over-ride, show up the first couple days of class and talk to the professor after class about the likelihood of your being able to add the class. Showing up for those first classes suggests that the professor can count on you to not fall behind in the class. Hate it when students show up in the third week because in my experience they are not serious students and will choose to waste my time and theirs. Try to understand that these over-rides have to go to graduating seniors first. If you’re a freshman, expect to attend several classes before you know you have the over-ride.</p>
