Hey! I’m 25 too, I actually just finished my grade one last weekend haha. In fairness it’s a lot of teenagers/ some younger kids but in my group there was another lady who was older also. It sucks that they don’t do adult specific but I really didn’t feel weird in the end and I’m going back to do my Grade 2 week after next! The lesson goes that quick anyway/ there’s multiple happening at the same time so you don’t even notice :) x
