Calmmmmm down, classes are small and they will call when they call. Even if someone else gets a call it doesnt mean you are unfortunately. They run on a point system and it even says in the job offer you may never be offered a class. So you need to make the decision that works best at the moment, if they havent called then you should go to TSA if your class is soon. Unless you want to roll the dice on PSA calling. Good luck
