I'd say #2. Failing is just a lesson that he should practice more. It is a part of everyone's life. Class should be enough to teach/remind him of lessons, but, just like an instrument. You must practice. That way he is excercising his body and mind and getting school credit. And you save money and get to spend more time with him. Sounds like a winner to me! Help hime practice and he will love it--maybe not at first. But he'll be so glad that you are interested in his progress.
