They must earn a grade of A, B, or C to pass a course at a university. However, some students do not attend their classes, so the percentage of their passing grades decreases because they miss their classes. There are many reasons why students do not attend college. Busy, sick, and at work are the main reasons for not taking a college course (Massingham and Herrington, 96). Some students are easy-going and skip college classes, and many consider themselves to be working. Students prefer to skip their classes and go to work because they may want to earn money. However, if students had a high number of absences, they were at risk of failing their courses. Even if students are busy or at work, they must attend their classes to pass them. Additionally, some students find excuses not to attend their classes because they don't want to study. For example, some students rely on their classmates to take notes on their lectures as an excuse to miss class. As a result, they struggle to pass final exams because they may not understand their classmates' grades and fail their classes. Students must be responsible for their attendance and manage their time because they do not want to fail.
