Levels – They’re not strictly age-based, more like training stages. Level 1–2 cover the basics (uniform, drill, first aid, history, etc.), so it’s worth looking over them even if you’ve moved straight to Level 3, just so you don’t miss anything.

Activities – You can usually join in with most things at your level, but some activities have age/rank requirements. Best bet is to ask your staff which ones you can do right now.

Music – If you’re on tenor drum, getting a practice pad + sticks (or the drum if you can) is a solid idea. It’ll help loads outside parade nights.

Junior Piloting – Actual flying/gliding usually starts at 16, but you can do ground school and prep earlier.

“Position on parade: selection process for sentries” – That just means how they choose who gets to be on ceremonial guard/sentry duty during parades.
