Why does everything else seem so interesting when you have to study? Let's find out how to stay focused(集中). Follow each piece of advice that is given below.

Turn Off Your Cell pbone

Nothing's worse for a teenager to stay without their cell phone even for a minute. It's the sound in your cell phone that stops you from learning. Stop sending text messages to your friends saying "I can't study" or "how much have you finished".

A New Timetable Every Day

One of my personal ways is creating a new timetable every day. Look at the clock, and divide your hours. Suppose 2 hours of study requires a 30-minute break after that. Relax and then go back to study for another two hours.

Try Different Places to Study

Looking for a quiet place can help you stay organized while studying. A lonely corner in your house is perfect. You can also go to your school library. This will work for sure, trust me.
