So good to him, Chris~
Cecil has no idea where Chris got this odd idea that he's good at everything. He isn't. He just works his butt off. That said, he's not particularly upset about his failure, just a little disappointed. But Chris coming over to encourage him makes him smile (see, he knew you were a good guy) and he thanks the other boy warmly. And, if he has time, he may just take him up on that offer! It seems like Chris is quite efficient with this, so he's sure he'd be a great teacher.
