"My instructor was professional, helpful in every way, pleasant, and often went out of her way to give extra help and assistance. I had many moments when I didn’t understand something and with the instructor’s assistance I had many (oh yeah now I understand) moments."

In addition to learning a lot, the classes are very dynamic and the teachers are fantastic, that's why the 4 hours a day go by very quickly.
