What's your problem? You seem to have been thinking of something.
I was thinking of the test tomorrow. I'm afraid I can't pass this time.
Cheer up. You've been working pretty hard these days, there's no doubt that you'll pass.
Actually, I'm just worried about the pressure, I always feel nervous as soon as I enter.
Try to relax, with the help of deep breathing. You can remove the pressure gradually. Take your time when you start to work. You'll feel much better in this way.
Thanks for your kind advice. You seem to be fully prepared for the test don't you?
I don't wait until tests come. If you work hard regularly, you are always ready for tests.
Nice talking with you. Have a good day.
