Characteristics of a Successful Student
Many high school or college students do not know what they should do to be successful in their studies. They understand good and bad grades in a general way, and they sense that they should attend classes, but that is where their knowledge begins and ends.
The following is a list of some characteristics of good students. The idea is to provide you with guidelines you can follow which will help you get down to the business of becoming a serious, successful student.
1) ___ They are on time. They listen and train themselves to pay attention. If they miss a session, they feel obligated to let the teacher know why before class begins, if possible, and their excuses are legitimate and reasonable.
2) ____ They demonstrate that they care about their grades and are willing to work to improve them. They often do not only compulsory, but also optional (frequently challenging) tasks that many students avoid.
3) ____ They don’t talk, read, or stare out of the windows. In other words, they are polite and respectful, even if they get a little bored. They also participate in class even if their attempts are a bit clumsy and difficult.
4) ____ They may see their teachers after the lesson as well in order to discuss their grades, listen to the teacher’s comments on their papers, and find out more about upcoming tests. These students demonstrate to the teacher that they are active participants in the learning process and that they take the job of being a student seriously.
5) ____ They take the time to produce a final product that looks good, and reflects their care and pride in their work. Successful students always try to complete their assignments. All work and assignments are turned in on time, even if some of their responses are not brilliant.
A) Successful students use every opportunity to make progress in their results.
B) They ask questions that many other students may also have.
C) Successful students attend classes regularly.
D) Successful students turn in assignments that look neat and sharp.
E) Successful students take responsibility for themselves and their actions.
F) Successful students are attentive in class.
G) Successful students contact their teacher not only during the class.
H) They make sure they get all missed assignments.
