There is no rule that one can only train in the Regular Classes (3rd floor dojo) from 3rd kyu. If you can handle the ukemi, then you can train in the Regular Class. If not, then the Beginner's Class is more apporpriate....Lisa
Interesting, this is what I was informed of with Doshu standing immediately in the background. Doshu interjected himself into the conversation and started asking a bunch of questions of me. He finally determined that it was OK for me to attend classes in the main hall and made the point of standing next to me and commenting about me during practice.
