There's a good article somewhere (I'll try to post later) about what a child doesn't learn if they are not challenged. Perseverance is one thing I'd like my child to learn, but he can't learn that if he never fails at anything because he already knows what they're teaching. I would prefer my child to get a hard-earned B than an A he did nothing at all to get. I think many teachers do not understand that we do not want our kids to get all A's!
It looks like everyone is giving you great advice, but I just thought I'd post the link that st pauli girl is referring to:
