I’m a senior student and I’m now in the need of your help although I can’t stand the great pressure.Every day I have to have lesson at school for nine hours and take at least three to four hours doing my homework at home. Our teenagers are eager to play and enjoy ourselves, but we hardly have any time to do that we want. Besides, we don’t even have enough sleep. There seem to have three cases about the overload: the pressure of examinations, too many homework and high expectations from the parents. We often warned that if we don’t do our best we won’t have the chance to go university. The pressure often makes me awake at night.
