Tell the clinician what feedback you got on you L2 exam. They are usually pretty open to what they teach. If someone doesn't ask for something, then they just have to pull something out of the hat. I think sometimes they actually like it when you say "Can you teach us this ...". You will likely got a lot of help on what to work on.
Then, work on you skiing through the first two months of the season.
If you don't do as well in spring snow, sign up for an exam in late Feb instead of early March.
