Exam result

        I was failed Chinese exam today . It made me unexpected . I sense that

Chinese has been difficult . It seems that Chinese is difficult than English .

I can solve the Maths easily . I have confidence that I can solve the English .

However , Chinese have became difficult . I think that I must improve my Chinese at

the summer holiday . It is my last item to hele myself !!!

        I wasted lots of time , I  am really regret that I wasted lots of time .

Why someone regret after they did some wrong ?
