After 5 days of waiting the midterm is over. It contain just some simple question from the homework and workout example. It’s not so hard, just have to spend some time to thinking. All credit goes to Dr. Agarwal and his stuff. Staff solutions will be available next week , it’s been said that all of your are encouraged to discuss the problems that you thought were particularly hard on the discussion forum. It is just halfway through the course. Study and be ready for the final grade.
