Sad things..

Today i get my quiz mark..And i'm really sad because my mark does not went as i want... Sometimes,i don't understand , why i don't get good mark..But,maybe because my study style is not effective... I really hope that my mark will change... I will try harder to get the best mark.. I have to be positive,not all things in life we can get.. Someday,i know that the day will come..Just be patient and keep up studying.. ^_^
