What do you do when an instructor returns an exam to you? Do you just look at the grade, or do you review the items you answered correctly and incorrectly? Review your graded tests because doing so will help you do better next time. You might find that your mistakes were the result of not following directions, being careless with words or numbers, or even thinking too hard about a multiple-choice question. Mistakes can help you learn, so refer to your textbook and notes to better understand the source and reason for each mistake. If you are a member of a study group, plan a test review with other group members; this allows you to learn from your mistakes as well as those of the others in the group.
