I only got up to grade 10 RCM myself. I find that post grade… I think 7 or 8 the difficulty curve becomes exponential with every level after. It is a pipe dream of mine to complete the teacher’s ARCT for real one day, so I still appreciate the suggestions! Thank you so much for talking shop with me!
I honestly think that there is more direct activity here. I asked the same question on reddit in 3 different places, but had more replies here than there.
