I'm researching all our options for science next year and will then weigh the pros/cons to make a decision. One thing we are considering is a homeschool co-op class where ds would be several years younger than the other students. Does anyone have experience with a similar arrangement? I would love to hear about your experience and advice. I will be contacting the instructor and co-op administrator soon, so any tips about that are appreciate (as well as how to prepare son for questions about his age, etc).
