<p>I think my son is probably going to major in math wherever he goes. Yes, he’s had a lot of physics but it apparently hasn’t been enough to propel him onto the physics olympiad team (been a semi-finalist twice) so he still has a lot to learn! 
He is doing some graduate level research at SDSU this summer but there are still a number of topics he hasn’t studied such as optics, quantum, particle, and nuclear physics. He did 5 semesters of lower division classes and 2 semesters of upper division. He audited 4 of those semesters for free and took the other 3 semesters at the local community college so the cost was minimal. He took all the AP physics exams (those were practically more expensive but we felt it best to do both CC classes and AP exams since different schools will accept different things) by his freshman year and he’ll audit optics this fall with the same prof he’s working with. So, while it seems he’s done a lot, there’s plenty more physics to learn and even more math he hasn’t learned and there are plenty of classes still to take, I’m pretty sure.</p>
<p>As background, my son considered matriculating full time in college 3-4 years early but each year, we decided it was best for him to wait until he was 18 to go full time; thus, he did end up with quite a few college credits but it won’t matter if he gets credit for classes; I think he just wants to keep enjoying learning wherever he goes.</p>
