Another strategy for maintaining your GPA is strategic class selection. There is a website called that allows students to post ratings of professors at their colleges. Other students use these reviews as a reference when making their schedules. Say you need to take biology, and it is a section that two professors teach. One professor assigns a ton of homework daily and gives pop quizzes while the other is an easy grader who gives no homework and only announced quizzes. You pick the second class because you have a better chance of getting a higher grade with an easy grader.
