Well, it looks like tomorrow is the day! You're getting lots of great advice here, and the only thing I'll do is reiterate the previous "relax" suggestions. I'm sure you are pretty amped up about it (you should be!), but the WORST thing you can do is go TFTS on us (Too Fast Too Soon). If you are too jacked up, and maybe you're not, but if you are, relax...belly breathe...find your happy place.
A lot of guys come in and feel like they're paying a ton of money for three days of speed, and they go out and try to go as fast as possible in every session to get the most for their money, or to try to impress us, or.... Resist that temptation! Concentrate more on applying the techniques discussed in the classroom, and on being precise to the extreme. Think methodical precision. Speed will be a result of that, and you'll get much MUCH more for your money.
Above all, HAVE FUN!!!!
