With either one, do you get a chance to get licensed? Door car or dragster?

I went to one (neither of the ones you mention) about 17 years ago, I chose the door car class. I learned a bunch but it was a frustrating experience since I didn't get licensed.

What I learned most of all was that I didn't know jack. It was scary getting into a detuned Pro Stocker without ever having been in a car with any sort of real power before. Out of the three of us in the door car group, only one made the licensing runs. The people in the dragster class had a much easier time, they all went down the track no problem.
