I would recommend that you DO NOT study before showing up to class. Relax and enjoy your time off. They will teach you everything when you show up to class. They will tell you when you need to start studying limitation and memory items. Listen to the instructors and you will be ok. You do not need to know how to build it, just what they want you to know. Have fun and enjoy your time in training. It's the best training program that I've been through.
