How to become a better student 

Maybe you are an average（普通的；平常的）student with an average intellect. You probably think you will never be a top student. This is not necessarily so. Anyone can become a better student if he or she wants to be. The following suggestions may be helpful to you.

56.

When you plan your week, you should make a list of things that you have to do. Be sure to set aside enough time to complete the work that you are normally assigned each week. Of course, studying shouldn’t occupy all of your free time. Don’t forget to set aside enough time for entertainment, hobbies and relaxation.

57.

Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything, but study materials. No radio or television. When you sit to work, concentrate/focus on the subject.

58.

This means looking a passage over quickly but thoroughly before you begin to read it more carefully. Scanning a passage lets you preview the material and get a general idea of the content. Scanning will help you double your reading speed and improve your comprehension.

59.

Take advantage of class time to listen to everything the teacher says. Real listening in class means less work later. Taking notes will help you remember what the teacher says.

60.

When you get home from school, go over your notes. Review the important points that your teacher mentions and you will remember them longer.

Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. Tests do more than just provide grades; they let you know what you need to study more, and they help to make your new knowledge permanent(长久的；永久的).
