If I could offer one piece of advice, it would be-
Since it's your first visit to the track I would encourage you to not take any preconceived ideas with you. I know that probably sounds just about impossible to do! The quality & depth of the classroom instruction is very important. Then you go out on the track for the first time & I can guarantee that it'll be (a) different from what you expected & (b) different from any road riding you've ever done!
If you set a target, such as attaining precision & consistency, on your first day you'll have achieved a lot. Just ride properly, don't force the pace & enjoy!
Oh, yes, and pics are mandatory
