<p>I find your son amusing. I am a high school student and I can say I am decend in physics. In fact, many students at my school are quite good a physics (800 SAT2…5s on AP…blahblah), but i think we put each other in check. Unless a student wins a place on the IPhO and the IMO at the same time and chooses to take IMO to win first place AND take a junior level physics course to have the highest grade in the class (This is actually a student from my grade at my school), I don’t think he/she can tell from high school level physics his/her physics level. I think your son can learn a lot just from people around him locally.</p>
