Classes are essential in everybody's learning process because they are a method by which schools function as one organization. The schools operate by aligning students according to their principles. Therefore, going to class is essential as they give students another perspective on materials in addition to the textbooks. However, in every school, there are the best classes and those that are the worst according to the students. It means that students have different views about different subjects in schools. I also happen to have my best and worst classes. My best class is Mathematics class, and my worst is Chemistry. Mathematics has some similarities and differences to Chemistry. Both Mathematics and Chemistry have group works and discussions and many summations.
