I am currently in enrolled in QC Academy, and I love it so far! I am just about to start Unit B (when my course materials arrive, any day). As far as I know the school is NOT accredited BUT there is a Worldwide Make Up Artist Certification when you finish at least with the Master Make Up Artistry program.
Also they talk about the freelance business, and you can do some of the business work optional (but totally worth it and thought provoking). So far my tutor is a MUA and has done work on Project Runway, and recently on the NY Fashion show. And it's pretty much one-on-one! It is pretty awesome so far. I plan on finishing through it before the fall.
