I did my cbt with zero experience. When the instructor asked us to move forward on the bikes I had to ask how I make it move, lol. Somehow, I passed the CBT and then passed DAS 1st time as well. I'm on my 2nd bike which is a 2005 Yamaha R6 and I love it! I hardly ue my car these days.
Don't worry about dropping the bikes, the training school bikes get dropped all the time. Better to get your dropping out of the way on their bikes than on your own!
