Because the result was generally bad, I have decided to cancel the whole test. Apparently, the correct solutions needed more time.
Instead, students will be given a new Exam 3 on Friday, March 10. This make up will cover the same set of problems. However, the questions will be formulated to fit the time limit.
An important remark: Not everything can be covered during the lectures. Therefore, students were (and will be) asked to learn selected parts using the textbook. In the case they need additional explanations, students can visit me or my T.A. during the office hours or to make an appointment.
