The calisthenics requirements are routines that will help you measure your progress and your current level. They help you set a goal to reach a certain level. They start directly at level two since level 1 is any person who trains calisthenics, no matter their abilities. The idea is that you prepare for each level for a while, and when you think you can overcome it, give it a try! They are routines that must be completed under a time limit, you must complete the marked repetitions of each exercise but you do not have to do them all in one round, but you can do as many as you need. Nonetheless, you do have to respect the order of the exercises.
