You always hear about “level 200″, “level 300″, and “level 400″ talks at conferences. Well, I have always wondered there was a standard rating system that all speakers agree to. If so, whose rating system would it be? I know that there is a standard system for rating movies (G, PG, PG13, R, NC17). I tried to create a Wikipedia page a few years ago but it got removed because of some reason or another. Probably because nobody agreed with me.
The document doesn’t list a 100 session level because Tech-Ed doesn’t contain any.
