Are You a Good or Bad Student? Being a good student is what everyone wants to believe they are. But in reality we all know that there are bad students. I, myself would like to believe I am a good student but when I looked over the facts it seems that I am not a bad or a good student. The first and foremost important quality of a good student is, of course, hard working. We can't have a good result in academic success without training and effort. The next quality is active in community. A good student should be highly appriciated not only by his academic success but by his social activities as well. In other words, a good person should be measured not only by what is he doing well for himself but also by what is he contributing for community. In addition, an active student means a comminicative skillful person in life and thus he is widening the chances to make friends with everybody around him and this is obviously a good thing we always want to, so that his college-life should be more fun and his confidence increasingly grow up.
Many surveys suggest students must understand concepts rather than just memorizing them. Memorized facts and theories will stay in students’ memories until they leave school, college, or university, but once out of school, the students will completely forget the core concepts that they learned. Therefore, it is essential that a good student understand the concepts.
