Relax and enjoy your time off before your class date. Come to initial refreshed and ready to learn. Don't waste time trying to study memory items/calls etc, before you start the first day.
For the rest of your career yu'll be working in a crew environment. Study with you classmates and you'll do much better than trying to do it on your own. Some of my best memories involve a case of beer, flash cards and 6 "pilots" in the conference room at the old Days Inn in Bloomington. Calling out limitations/memory items while tossing a tennis ball around. It's tough but it's a blast and never forget that the training department is a service to you. Ask questions, utilize your rescources, classmates etc. Have fun! Make the best out of a challenging learning experience.
