Feel good about my exam

I took Exam today, and I though I did well enough but didn't do well enough like what I wanted because I didn't know the answer for some of questions like last few of them. However turned out that questions I answered was correct and I think I got all of them right this exam. :D
(今日は試験がありました。そしてすごくできたと思うのですが、最後の方の数問がわからなくて間違ったかもと思って家に帰ってきて授業と習ったことを確認したらなんと！全部あっていました！
♪───Ｏ（≧∇≦）Ｏ────♪
もしかすると100点とれた！？(^-^)/ と思っています)

Well just wanna wright down some of what I though after I took my exam today!
