DeuceKV Rookie Southern Indiana

I had a buddy who was recently hired at KIND (up/down) facility and we began chatting about the differences between Center and Tower training. He originally wanted ZID but took the first offer given to him.

I want a center as well but he made me extremely nervous talking about how hard the training is in OKC for center and half of the class washing out etc.

Is there anyone who actually is going through that training or already received that training that can be insightful to this? If you study hard and bust your balls down there is still that hard for you to get through?

Any info would be appreciated...thanks!
