A test score is ONLY a measure of what a student scored on a test.
• If you are very anxious, and blank out, then your grade can not measure what you learned.
• The reverse is also true. If you are good at taking tests and a lucky guesser, the score won't be an accurate reflection of what you have learned.
.....So, don't underestimate the importance of tests, BUT, be sure to keep them in perspective!
