Dear Miss Chiu,
I would like to inform you that I did fine in the oral exam last week as those candidates did not say much, I could then have a chance to lead the conversation and ask them questions. I just wanna say a big thank you to you cos I am really grateful to have you as my teacher. You have contributed so much to us and help us wholeheartedly; without your guidance, hardly can I imagine what my performance will be like in the exam. Anyway, I will keep you updated with my results when they are out.
