I'm also going with the notion that your coach will see what you need to work on each session and be able to give you the best guidance there is. Surely you can have personal goals of your own, and speaking with your coach is the best way to understand if your goals are inline with areas that you need to be improving on.
My *personal* progression was much like this:
Completed first level 4, was worlds better riding a motorcycle
Needed to work on body position, especially between my right and left turns, and being able to feel more 'loose' and comfortable on the bike.
Once I sorted out that, I was able to start going faster through corners. I needed to then roll back to the most basic of visual skills, the two step, in order to start feeling more comfortable with the speed.
Working fairly well with the two step in corners, I then needed to turn the bike faster, quick turn.
Now I needed to work on drive out of corners, the pickup.
So basically, you are always going to be going back to the basics, in my experience.
This season I want to work on my reference points. The coaches have noticed I am extremely good in certain corners, and other corners I am lacking. When they ask me to think about why, I realized it's because I was very comfortable with my reference points on my best corners.
