Thanks everyone for all the great tips. Wow you guys are great! I will definitely get my hands on the videos. I had no idea he knew so much about atoms, mass, etc until last week. Sheesh how do you guys keep up with curriculum? I feel like the second I get something he either learns it overnight or already knows it, so I am trying to figure out where to begin so we can plug some holes.

About the downside, I asked my son to come up with a pros and cons list so we could discuss potential issues he thinks he will encounter, his response was very similiar to yours Kriston. However, as a "mama bear" I am worried about bullying. He will be a 1-2 years younger than his classmates. He has a summer bday. Any one deal with this with a grade skip?

Shari, are all your kiddos GT? How in the world do you do it?
