How are the quizzes graded?
The grade is calculated on the basis of how many questions the student answered correctly. Every time a question is answered incorrectly, points are taken off based on how many questions are on the quiz. If there are only four questions, for example, and the student gets only three correct, his grade would be 75%. Points are added back, however, when the student goes back and corrects the answer. He can do this as long as there is still time left for the test.
