My only experience is with one bootcamp, but people rarely don't graduate. That wasn't because they just pushed people through, but filter people out at the beginning. A month of online prework helped filter out those who couldn't handle it, as well as a test at the end of it. If you were someone who wasn't keeping up, they might hold you back (there was two sessions, junior/senior phases). And in a rare case, you may get asked to leave.
