"Classic" pattern is different from modern AMA pattern because we fly with very different airplanes and in a non-turnaround style. Most of our airplanes are not the tail wheel airplanes commonly found at a pattern competition. Non-turnaround is where you basically set up a ways out and then come in and execute a maneuver at around midfield. You fly back and forth until your predefined sequence of maneuvers is over. Maneuvers are judged on accuracy and awarded points. It's fun and adds precision and discipline to your flying. Practice it for a few years and you will be amazed how much better your piloting skills become. It's addictive!
