If you get to a McDojo, it doesn't really matter how good you think you are at other martial arts, you'll still be at a $hit school.
There is a LOT of focus on blocks, kicks, etc. And you will obviously spar as well.
introducing about style, history, sifu, friends, etc

I will be attending my first Taekwondo class next Monday and I am excited. I know Muay Thai and BJJ. I have read that taekwondo is not effective but I believe if you know many martial arts then it's effective. What will I expect in my first class? What will I learn? Will it miss up my kicks from Muay Thai? What should I wear or bring to the first day of class?
