Reminder: Tutoring Tomorrow, Thursday Feb 28
I will be holding office hours/tutoring tomorrow in Room 302 from 2:45pm-3:45pm.
Sound and Light Retake Instructions (Due Fri March 1)
Here are the instructions for the Sound and Light Quiz retake. You are only eligible if you scored 15 points or below.
1. For every answer you got wrong, on a separate sheet of paper, write the number of the problem, your original answer, the correct answer, and 3-5 sentences describing why the answer you chose on the test was incorrect. The sentences are the most important part of the retake; they will determine your retake score. Your paper should look like this:
Problem:5
My Answer: B
Correct Answer: C
I answered B. This is incorrect because...
2. Staple your retake sheet(s) to the front of your sound and light quiz, and turn it in at the beginning of class on Friday.
3. The paper with your corrected answers will be graded as follows:
If you get everything right, including your thoughtful written responses to why your original answer was incorrect, your grade for the quiz will go up by one letter (to a maximum of a B)
If you get at least half of the corrected answers right, your grade for the quiz will go up by one-half letter (to a maximum of a B)
If you get fewer than half of the corrected answers right, your grade for the quiz will remain unchanged.
