Replying to Windells Skill Levels

So I just got the okay from my parents to go to Windells this summer. I understand they group it by skill levels. I think I could be in the advanced group because when they show most of the banger shots from campers in the edits I think I am as good. On rails and boxes the best tricks I can do are k-feds, 2 on - 2 off, front 4's, super - feds and switch lip back 2's. Jumps, clean 9, 720 safety, and backflip. I can hit just about any feature in parks. Jumps I hit up to 50 footers, but the rest just scare the absolute shit out of me. So would I be in the advanced group or the intermediate? Answers would be great please.
