The structure of a gymnastics routine

Compulsory routine
A routine comprised of eight specific skills that are required of all athletes and two skills that athletes choose themselves.

Degree of difficulty
The prescribed rating for each skill according to the code of points. The ratings for every skill performed are added together for the complete difficulty score.  

The athlete's form, such as whether the body line is kept straight, legs are together and landings are near the center of the bed, as assessed by a panel of five judges. The complete execution score is calculated by eliminating the highest and lowest of the five judges' scores, and adding together the middle three scores. Each judge scores the athlete out of 10 points. The maximum total execution score is 30 (10 + 10 + 10).

A straight jump at 3/4 height performed as the last jump in a routine.

Time of flight
The amount of time spent in the air, not in contact with the bed.

Voluntary routine
