I think all high academic kids should take the SAT very early, and a 4.1 GPA qualifies as that. I had all three of my student athletes take the SAT as freshman. The recruiting process is as much an elimination process as a selection process. If your 4.1 gets an equivalent SAT than you can eliminate many schools that are academically below his ability. Also the more you take the SAT the more comfortable you are with the test. There is no downside as if the scores are not what you like you don't have to share them.
