I took a community college class in programming, and also went to a bootcamp. The college class had 40+ people in the beginning, maybe 30 at the end, 3 months later. We spent a week on basic for-loops. I was one of 5 female folks in the beginning, and only 3 of us made it to the end. There were some absolutely intolerable know-it-all teenage boys that made me seriously reconsider my interest in programming, despite getting over 100% in the class (through extra credit and curved tests). At the end of the class I had a commandline game, and had no idea how to do anything but basic programming. The bootcamp I went to was about the same duration. There were ~35 of us, and every single one made it to the end. We were explicitly taught how to work well with each other. At the end of the bootcamp I knew about all kinds of things from databases to css, and had made several complete projects. I hear what you're saying about community college being a good way to try it out, but it's in no way comparable to a full codeschool course. I think Holberton school is multiple years, too, rather than a standard 3 month program like the one I went to.
