Mistake

I went to school to take an exam in time which I thought was correct but incorrect actually. So I couldn't take the test. The only one thing to make me feel easy is the fact that I will get the grade without taking the exam. I studied (little) and the questions must have been easy. (Unfortunately, it's not joking but real.) If I had taken it, I would get the best grade. You should learn from mistakes. Never do like it again.
