It almost seems as if there should be a book or a website the gist of which is: "If you can't and don't want to plug through the concepts and problems here, you're wasting your money to go to a bootcamp."

Heck, there are "intro" (OK, some of them aren't really) MOOC classes that, while more theoretical in some cases, should give you a pretty good idea if this is something you're really willing to devote a lot of time and money to.
