Which info do you need in your country to find only your class once you know graduation year and grade? I mean only your class, not all classes from same year and grade. Do have classes own names in colleges or high schools? How many years do you stay in class with same name? Do you need to change every year your classmates? Do you even need to know grade to find a class if you know the name of class? Please explain me how is about that in your country. Thank you very much! Ernest
3 years same in primary , middle , high school normally changing is not allowed unless parents get transferred to some other city/villages
