CNA CLASSES!!!

hey, I recently got information from two different schools offering cna classes. On is at a technical high school, which offers it through their adult program. And the other Is at a community college, offering it through their continuing education program. Before I planned to go to the technical school, who's price is $590, but their classes are all filled, so I got info from the college which said their price was $350. I know that these prices does not include, book fees and testing fees, But the thing is, $350 is pretty darn cheap compared to $590.. So I was wondering if maybe there may be a reason for why one is cheaper? Does it possibly offer less? Anyone know why that could be?
