I found the 'Lead & Follow' approach an effective way in learning the proper line around this course.  The pace started conservatively, and the instructor did a good job monitoring the group so that we could increase our speeds in subsequent lap sessions.  
The one additional thing I wished I had gotten out of this class was to have had an instructor in the car earlier in the day, so that I could have gotten specific feedback on turn-in points and shifting strategy.  Nevertheless, the class provided plenty of seat time and I got lots of practice in point-bys.
