From a novice perspective, I was a bit worried going in that the class wouldn't be 'tuned' to my skill level. I was very wrong, Chris, Jourdan and Dustin were able to keep giving me things to work on in each of the drills and sessions that helped me make incremental improvements each time out.
By the end of the second day I was lapping a good 8s faster than previously, even with limiting my main straight speeds 20mph slower as I still have a lot of work to get turn 3 right.
Besides the instructors, I even learned a ton from the other students.
Was a great two days, at a really fun track.
