Ann Whimey, a sophomore(大学二年级学生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer."

The young student was experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the great nervousness. though poor scores are often a result of poor study habits, sometimes test anxiety causes low scores. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.

Special university counseling(咨询) courses try to help students. In these courses, counselors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the test shows their anxiety is high, the students can take courses to help them deal with their nervousness. These courses teach students how to relax their bodies. By controlling their nervousness, they can let their minds work at ease, learn information, then come out without difficulty in a test.

An expert at the University of California explains, "With almost all students, relaxation is felt after taking our program. Most of them have better control during their test. Almost all have some improvements. For some, the improvement is very great.
