Our books and classroom instruction go together like Hall and Oates. On their own, they're excellent, but together they're legendary. So yes, ideally the path to Nerdvana should include a stop at one of our bootcamps.
But maybe you've got a very good reason for missing out on our classes (say, the sun suddenly burns out, or your home is swallowed by a sinkhole). In that case, our books do a wonderful solo act.
