Billy N's review covers the details very well for the 4 Day Grand Prix course, so I won't retype them.
One thing I will add is that the drills in the first two days are applicable to both the rest of the course and street driving so, they are definitely worth the time spent on them.
From my experience with the heat on the track, don't hesitate to take a break when you need one, there is plenty of seat time in the course!
From the moment you walk in until the moment you leave, everyone is professional and relaxed to make sure you have a good time and learn all you can.
Thanks to Brennan, Instructors William and Robert, Marissa at the desk, and of course Bob Bondurant for executing a great week for me and the rest of our class!
