     Knowing the best way to study will help you to be a better student. By using your time properly, you

can do your homework more quickly. Learning to study is not difficult.

     The first thing to remember is that you must be willing to learn. It doesn't mean that you must always

like the subject. It does mean, however, that you must be willing to do whatever is necessary to learn. Try

to understand why it is important and how it will help you now and later to do and learn other things.

Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of

writing easier. Sometimes the subject that you think is going to be uninteresting will be exciting when you

begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work

with them.

    Here's some advice for you: have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions; have everything ready before you sit

down to study, a dictionary, paper, a pen and books; be sure you understand what you should learn

before you start; read carefully and pay special attention to the most important things; when memorizing,

first find out the main parts and then recite the whole thing; check your homework after you finish it; never

forget the importance of review and preview.

    Don't try to spend a lot of time researching learning methods. There are many students who know many good learning methods but don't study well. They forget that the most useful learning method is to study

hard.
