  • Oct 20, 2011: Midterm Grades

The grades for your midterm has been posted on the NYU Blackboard. I will shortly make up a tentative grade for your overall performance, based on midterm and hw1-3. Note that NYU's rules for exams are that we have to keep the exam answers for up to 5 years. Hence, during recitation today, the TA will handout the midterm to you and allow you 10 minutes to go through it. After that he will collect it back.
-- Please verify that your points are correctly added up.
-- Make notes about any questions you may have.
I will keep the exam answer sheets in my office. You can come during office hours or make an appointment to come see them anytime, and to discuss any concerns.
