Argree with Big Ape.. do your DAS and then go and get some more training
In my opinon all the teach you on your DAS course is to pass your test, not actually how to ride... just take your time and dont rush, also avoid going out in big groups after you pass, go out by yourself then you can ride at your own speed and wont feel forced into going faster than you want to just to keep up.
