I used this quiz after completing a practice worksheet provided by CScope, but it could stand alone for more independent students. You could also use it for homework, since it is less rigorous than a daily worksheet. I've also included a key on pages 3 and 4. Using the letters may seem a little weird, but I did it so the students could use their student responders -- "clickers". I've really dedicated myself to using mine this year. It cuts down on my grading, and my students seem to really enjoy immediately seeing their grade.
