Mountain's snowboard level scale

I am a motivated beginner, I have no experience snowboarding/ I have a few hour or days of experience on a snowboard, but I feel unsafe and uncertain and I would like to go back to basics. 

I can already turn (Hillside to toe side) on the beginner’s slope and would like to add a flow to my style, increase my control in high speed and link turns. Eventually I’d like to be able to handle steeper slopes. 

I can control my speed and direction, on the beginners slopes I manage to link turns while maintaining my speed; I’d like to ride some steeper slopes and improve my boarding style.

I feel safe and in control, while boarding blue and easy red runs, I link my turns while maintaining my speed; I manage to do a basic switching rides/turns while boarding in easy terrain.

I feel safe and in control, on every piste in the site; I can curve well and have a minimal drift on steep pistes; I’ve been to the park and could perform simple tricks/ been off piste (by the side of the piste) and managed to board. I’d like to improve my performance in the park and off piste.

I feel safe and in control, on every piste in the site- also if icy or bumpy (muggles) without any problem while maintaining a good style; I have some off piste experience.

I can snowboard well in any terrain on and off piste- expert snowboarder.
