How can I study hard !.!.!.!

In Cambodia there are a lot of school but when you study you need to find the school that have high quality . If you didn't find the school correct you will spent a lot of time and money , but if you find the correct school is expensive but have high quality . Some student want to be good student they try to study hard but cannot be good student because cannot find the correct school , the teacher didn't care and don't teach the student .sometime when time to teach but teacher come class late or upsen alot , so the student feel lazy . If you want to find the good school you should choose Ace , Ace stand for " Australia centre of education ". why I say Ace is good school because Ace have good rule when time to study the student didn't need take phone into class , if you take you should close or put silent if you don't put you will disterb other student that they study with you . Teacher in Ace always have alot experian teach at other school . If you want to be student in Ace you need do test first , but if you 15years old you can go study GEP or if you want to study at younglearner you can choose .
