There is no quiz for this session.
There are no videos or reading for this session. Just keep working hard on the projects in previous sessions.
Test 3 is coming up soon (see the aside to the right). Try your best to be caught up by this session so that you have plenty of time to do the Practice Problems that help you prepare for Test 3.
There WILL be Preparation to do for Session 22 (that is, preparation for Test 3), as well as important preparation for Session 23 (project starts).
