[Cs3] homework quizzes

[Mikhail Nesterenko]

CS3 students,

I had several requests from you for further homework quzzes. I am
surprised and heartened by this: students seldom ask for more
work. This feature is "experimental": Joseph and I are making the
quizzes up as we go. Now, coming up with good multiple choice question
is hard and it takes a lot more time that it seems. So we promise to
put some effort and add quizzes. This spring break might be a good
time for that. I'll email you as soon as another quiz is put up.

Thanks,
