Try asking him or her any of the unanswered questions in this category. Any of the questions in this category about Taekwondo organizations would be good, too, but it's a very bad idea to challenge your instructor.
Unless he specifically asked you to try to challenge him, i'd recommend against doing so- You are a student, your instructor is your teacher. you are there to learn from him or her, and better yourself (hopefully), not to issue challenges to someone willing to share their experience with you. it's disrespectful to go out of your way to try and challenge someone who is not only your instructor, but also (I assume from your question) A superior rank.
Why would you want to challenge your instructor? You are supposed to be challenging yourself, not trying to embarrass your instructors. The best question to ask him is "How can I be better?"
It depends on your instructor and the effort you put into to learning them.
Follow the guidelines of your instructor and write one.
An open mind, a willing & positive attitude, and a qualified instructor.
In the ATA you can ask your instructor if you could buy your rank appropriate video.
First off tae kwon do is not a sport so don't call it that. Second yes if you sign up for quality tae kwon do lessons you can lose weight.
You find an instructor and learn from them. There are many dojo in the US and much of the world that teach this style. Closely related would be Tai Kwon Do.
There's no standard on headgear, but ask your instructor and see what he recommends.
It is probably "kamsahamnida" or "komapsumnida", which mean "thank you" in Korean. However, you should ask him/her. Your "sabeomnim" (Master Instructor) appreciates your questions.
generally he takes the notes right on your testing sheet! he gives it to you at the end so you can see what you need to improve on and what you did on.
When our instructor wrote on our doboks (uniforms) in Korean, he was writing our names. I think it helped him learn our names, and it certainly helped our Korean master refer to us by name during our belt test.
This would depend on the instructor of the school. The school that I go to accepts children around the age of 4 years old.
