Every student spends lots of time studying and almost everyone would like their study to be more efficient (高效的). Here are two ways to help you manage your time better when studying.

Your study environment

Watching TV while studying is a bad idea and makes your study ineffective (无效的). So you’d better turn off the TV while you’re studying. Some students like listening to music while studying. Music is OK, but whether it helps or hurts depends on whether it can keep your mind at peace. Make sure that any music you listen to is actually helping you study, but not drawing your attention away. Good lighting and temperature are necessary, too. When it’s too hot or too cold, it will be harder for you to give all your attention to what you are working on.

Full attention for at least 40 minutes at a time

One of the most important things you can do to study efficiently is to give all the attention to your study for at least 40 minutes at a time. Don’t let anything else draw your attention away from the study during the period. Then have a rest and relax. Don’t study for too long a time because your brain gets tired and it needs a rest.

If you choose these ways, you will make an improvement in how you manage your time for study.
