not all Chinese are intelligent as you. I don't recall College is the place to learn multiplication, subtraction, division and addition. The comment you've made is somewhat offensive to some people. I'm a College student however I don't mind it because I agree with ya. But you must understand that people going to College for a reason, either they lack financial supports or made many wrong decisions (that is me) back in high school or language barrier as well as many other reasons where we cannot foresee.
