You have an upcoming exam and you are confident that you have read all your books and believe you know your stuff down cold. Somehow, after sitting for your exam, you fail. To avoid this from happening again, you can use methods like SQRW or KWL to make sure that you get a better grade. Each of these techniques are initials that stand for “Survey”, “Question”, “Read”, and “Write” (SQRW) and “Know,” “Want to Know,” and “Learned” (KWL) respectively.
