No quizz on April 10th.

Midterm Exam Spring Break work: work (re-do) your Midterm Exam during the spring break. Write all the answers and solutions clearly (in a booklet or on a paper - up to you) to all the questions (even if you did the right). Submit it on Tuesday, April 10th in class (no late submissions!). I will return it to you on the day of the final exam, so make sure you keep a copy of it for preparation. If everything looks good, you will get half of the points you didn't score on the Midterm Exam towards your Midterm Exam grade (up to 100 points).

For example: you got 40 points on the exam.
I looked through your re-make and everything it good.
So I will add (100-40)/2 = 30 points towards your score, which will make it 70 points on the Midterm Exam. 		HW14:
