Check the info clues at the start when you pick up the card, if there's anything you don't understand just ask the organiser and they'll usually explain what you're looking for, I couldn't remember what a "gabel end" was at 6am sometime last year and they happily explained which bit of the barn I needed to count windows on and I drew a little picture on the card incase I forgot :)
