Hey, I can't exactly remember requirements but here was my routine for Level 8 last year.
- Full Turn
- Cartwheel Round off series
- Switch Leap Split Jump Series
- Backhandspring
- Split Jump
- Front Layout 1/2 Dismount
You deffinately need a full turn.
Some series could be cartwheel round off, back walkover backhandspring, backhandspring backhandspring.
I believe you need 4 A's and 4 B's.
