High school students who feel anxious about tests and procrastinate on their schoolwork tend to have lower grades. On the other hand, students with supportive families who encourage academic success tend to have higher grades. A study of 496 high school students found that feeling tense or having physical symptoms before a test, as well as positive family attitudes, predict better end-of-term grades. Conversely, worrying about tests, thinking about irrelevant things during tests, and procrastinating on schoolwork predict lower grades. These findings suggest that managing test anxiety, avoiding procrastination, and fostering a supportive family environment can help students achieve better academic success.
