Don't worry. I'm sure you'll do better next time.
I didn't realize it was so difficult though I know I'm always too nervous in such competition.
It doesn't matter. Forget it.
I don't think I performed well.
Oh! That's much hetter than I did.
Can you tell me how to improve myself?
There's no secret at all. The only thing for you to do is to practice more. You will succeed.
Thank you for your encouragement.
