OMG! class tomorrow

Class starts tomorrow, and i really need to relax for a while! I have too many classes, and i think i really need to work hard to achieve this goal.  I actually have 3 kinds of age, the first one is that i am seventh grade, cause in Taiwan, i am still going from seventh grade to eight grade, the second is that i am eighth grade going to ninth grade, which is what i should be now, but,  the third one is going from ninth grade to tenth grade, which is very annoying, cause i need to study a lot harder! i really hate to study!
