Tests usually cause anxiety in students. Students learn to become anxious when they take tests because they are graded and evaluated. But if a teacher starts giving tests in which students are given a second chance to improve their grades, test anxiety may diminish. After a vacation, however, the first self-graded test may elicit more nervousness from students than did the last self-graded test given before the vacation.
