Qn = percentage of correct answers for question n.
Tn = percentage of students getting a total of n questions correct.
Cn = percentage of students getting a total of n or more questions correct.
(So for Set 5, for example, 71% got question 3 correct, 34% got three questions correct, and 53% got three or more correct.)
