What an unluckly day.......

Yesterday,I already knew that today will be a tough day for me but I really didn't know it's so terrible,horrible and unluckly..... The subjects that I sit today are kh,bm(1) and chinese(2)... The thing that I can't imagine is that I'm going to get ''b'' in my exam.......I really don't know what happen to me today... I can't sit down properly,I can't controll my heart beats......And I had just done ''中楷'' after an hour of the exam..... What a drag........Finally,I done all of them but the standard of my essays are terrible!!!!!!!! Haiz....I just can work harder with that and make sure that other subjects will be all fine........
