It starts with the "C" section. If students only answer all of the questions in this section, that is the grade they receive. The middle of the sheet is the "B" section. This section is a bit more challenging. If students answer all questions in the "C" and "B" sections correctly, the earn a B on the assignment. The last section is the "A" section, and the most challenging section. If students answer all questions in this section as well as the other two, they will earn an A on the assignment.
