miss the exam ?

On my way home, suddenly, I recalled that I should had sign up to participate the English interpretation test. I remembered that June 20 was the first day on which we could enter for the examination. But until now, 5:45 June 24, I hadn\\\'t entered my name.
I got very frightened and began blaming myself. I had decided to take part in the exam, although I was not sure I can pass, but what a pity if I lost the chance because of my forgetting to sign up, as you found that game was over before you were to play the game.
It\\\'s terrible and I began to think how to make up if I really missed the exam...
