Jared Wyatt [email (add @nyu.edu): jared.wyatt] is the IA for our class. In addition to running the recitation, he holds office hours and is also available by appointment.
Your professor has scheduled office hours. If you have questions about the course material, you should drop by his office. If you cannot attend the scheduled office hours, feel free to make an appointment with your professor. If at any time you are falling behind or are overwhelmed by the material contact your professor.
