As a rule in Ms. Walker's class, before each exam each student is provided with a study guide complete with questions to answer. To ensure that the students even look at the study guide, they must submit the answers to the study guide on the day of the exam. Students who do not have the completed study guide must submit the study guide, along with taking a modified, advanced version of the test. According to a parent, this policy is unfair, and the study guide rule should not exist. Is this an unfair rule and practice?
