Failed the driving test

I had token a driving test today, but it was failed. I am a little bit sad now. I am studying hard these days.I had confident that i would pass today,also my driving teacher believed too.But at the end, we all disappointed.

I did great at the beginning and the middle of the test. When i turn back to DMV, it's the unlucky beginning.The tester asked me to turn right at the cross-street, the light was red at that time.I stopped at first, then i took off the brake and looked around,when i saw no car go straight, i began to turn.Suddenly, the tester stepped on the brake.That scared me.I began to be nervous.She looked at me and said,"did you see the left turn light on green?You must wait until the left light on red.Then you can turn right.You turn right was wrong,that's dangerous."

I did wrong at the last right turn.That's so pity.Oh, so sad now. I hope i won't make this happen again.I hope i can pass at the second time.
