The Pomodoro technique is one of the most used study technique in the world. What you do is: work hard and stay focused for 25 minutes, without any interruptions, and after that, you can reward yourself for good work. The break should not be that long: between 5-10 minutes and then you repeat this.
The Pomodoro can be used by anyone and it is a good help for getting better grades. One set of work only takes 25 minutes, and give therefore more moivasjon to work with things you maybe don’t won’t to. This is very effective working and you get a short break to do whatever you want. You feel better because of the work and it is very easy to get into the flow.
I think the Pomodoro easy to get used to after school, and sometimes at school. You can keep the motivation up, and therefore easy to stay focused for 25 minutes. I recommend it to every student out there.
