AWAC training is super laid back. Don't spend any money... there is definitely no need to do that. If you have already made it through training for the Dash, than I am sure you won't have any problem here... If I made it through, anyone can!
As long as you have a good attitude and you fit in, they will work with you until you get it, but as i said before I have no doubt that you will be able to handle it.
