Just consider it as an IQ test. (not a standard IQ test )

cos in china....we can not have a fair choice.. that's the problem of our society. we cannot always get what we want by out own efforts but by your background relationships. so if the exam is cancelled,then situation would be worse. then good student will never be in the best college but those guys with rich parents.which is disgusting in china,if you refuse something rationally sometimes relationships will be affected..but not in other countries so...that's why you live here and you must face it
