Hard Work Has Paid Off

I went to see my calculus test sheet early in this day , and I got a good grade .But I don't think it is due to my intelligence , in fact , I am stupid in some aspects , rather , it is because of hard work , (I did so many calculus problems during this semester , especially recent days.). But I also lost something , that is , I paid little attention to my general chemistry course , even though the scores have not been announced yet ,I don't think I can have good grades on this subject . Maybe I need to manage my time more efficiently next semester...
