In my opinion, having tests, quizzes, and homework assignments throughout the semester is better for students. First of all, tests, quizzes and homework can make students study every day. Review is the most important thing during study and let students remember knowledge. Second, students feel less pressure because tests, quizzes and homework are through one chapter not all the chapters. For example, students can use less time to study a little knowledge instead of costing much time to review all the knowledge. Finally, tests, quizzes and homework can let teacher master the situations of students and adjust the process of class. In conclusion, I prefer to choose tests, quizzes and homework as a checking tool.
