Which ski level am I? (1 to 7)

Hi everyone, This season I'll attend an advanced ski course in Europe and is required to give my ski level (1 to 7). I'm pretty confused by how the gradings works so it would be helpful to hear from an expert. BTW if you have any observations or tips about my skiing let me know! (I would love to drag my hip :) Skis are Salomon S/Race Prime GS R:21m Thanks in advance
