Im 16, really want to become a professional dancer, what courses or classes do I need to take to achieve it?

As they are not good dancers but more like gymnasts this question is moot! All they do is things that show off flexibility and tricks while their form is generally poor. If you want to be like them take acro in competition dance and be born with natural flexibility.

Expect lots of problems when you get older do to pushing joints beyond their natural capabilities.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
