Class 17, ICA #16, October 2.

There were 6 clicker questions. The first few
were on the lecture-tutorial on Kepler's second law that
we did on Sept 30.

You get 1 mark for answering each question, and you
get 1 more mark each for getting questions 1, 2, and 3
right. So there's a total of 9 marks for the day.
The clicker questions count for a total of 3 points toward your
course grade, so your points for the day = # of marks * (3/9).
