You'll be fine. Study limitations, systems, memory items, THEN flows and profiles. Get a group from class together and study at night. Don't kill yourself hitting the books. Take time to relax. I think its 1 week of indoc, 3-4 weeks systems, 2-3 weeks sim, 1-2 weeks OE (line training). Its been a while, the guys that have been through more recently could tell you more. Congrats!
