1) Decide the time for studying. If you decide the time for studying, you’ll be used to studying.
2) Improve your meals. We need enough nutrition to study so you should think about your meals. Did you have a breakfast today? If you didn’t, it’s not really good for your brain. Maybe, you can’t concentrate on your studying.
3) Do not try and work too hard!! If you work too hard, you will hate to study and you don’t want to study any more. The most important thing for studying is motivation so you should try to like studying. Take it easy!!
