Your gym will still need to do at least one level 5 meet to score the girls out of compulsories. For that meet, they will need these new skills:
floor: 180 degrees split/switch leap, full turn, rbhsbt, fhsfhs, ft.
beam: full turn, back walkover, 2 second handstand.
bars: cast to horizontal, baby giant, flywaway dismount.
For level 6, you will need As and Bs. Since it is an optional level, you have choices. But the most common choices are:
floor: switch leap to 180, fhsft, rbhsbt, full or 1.5 turn, 180 straddle leap, tuck jump.
beam: bhs, bwo, full turn, 180 leap, ft or bt dismount
bars: cast (at least above horizontal but as close to handstand as possible) on high and low bars, flyaway dismount from (as close as possible to) handstand
