nowadays,many students have difficulties in study,also including me.what shall we do to change this situation?
first,you should change the ways you learn.change the bad habits such as talking or sleeping in class,eating in class or looking at other's homework instead of you done it yourself.It is very important to listen carfully in class.Second,you should communicate with the teachers regularly.This can help the teachers know more about your study.It just like a disease known is half the cure.Third,remember to review the things you have learnt everyday.If you do this,you can do well in the exams.
If you can do all the things above,you can study with happiness.
