Although graduation is approaching, I still have three circles of hell that I must go through. Namely, AP Physics B exam, AP English Language and Composition exam, and Senior finals. I sincerely believe that I can score pretty good on all of them. However, the shadow of doubt is thrown into my mind by four vicious words- should have and could have. This year I should have done some thing better, and could have done much more. But these words won't change anything now- I have no time left. There is only one thing I can do now- go through these circles. But let me forget these sad thoughts. Today is Mother's Day! Don't forget to congratulate them-those tender guardians of our childhood.
