- Attendance and Grades Read the following on attendance and grades, and answer the questions in the discussion board. A study conducted at Manatee Community College revealed that students who attended class 95 to 100% of the time usually received an A in the class.

Students who attended class less than 80% of the time usually received a D or an F or eventually withdrew from the class. Based on this information, attendance and grades are related. The more you attend class, the more likely you will receive a higher grade. If you improve your attendance, your grades will probably improve. Many factors affect your grade in a course. One factor that you have considerable control over is attendance. You can increase your opportunities for learning by attending class more often. a. What are the variables under study? b.
