[cs33211] quizzes added

[Mikhail Nesterenko]

OS students,

This is just to confirm that we will have quizzes this semester. They
are 10 points each. Multiple choice. Will be held in the first 10
minutes of the class. They are not surprise quizzes: they will be
announced at least a week in advance. The quizzes will cover the
material of the lectures. Your worst score will be dropped. That is,
the maximum number of points you can get for the quizzes is 20.

Thanks,
