There isn't consistency in the quality of classes and instructors. For example, our instructor for the chemical phase was awful. There was next to no hands on, she did not care about us as students in the slightest, and she viewed class time as her time to talk about her personal life. It was ridiculous. When our class tells another instructor or student who our teacher was for that phase, the response is a knowing and sympathetic "Oooooooh".
On the flip side, the instructor we had for styling took time with each student individually to make sure they were on the same page as everyone else. It was obvious she loved what she was doing, and loved teaching. She was professional and friendly and caring.
There were also a couple phases that I feel like wasted an immense amount of time. The business phase in particular could have been done entirely at home in less than half the time. There wasn't any really teaching happening. It was just DVDs. That time could have been better spent getting more hands on experience.
