<p>Sorry about that - guess I wasn’t very clear. Our district (state actually) will pay for the students who have exhausted the HS curriculum to take classes at a local college. So next (junior) year he’ll be taking Multivariate Calc, Differential Equations, Organic Chemistry and Mechanical Engineering (over 2 semesters) at the college, in addition to 5 HS classes. Unfortunately, while it is a state 4 year college, it’s certainly not one that focuses on those areas. However, by senior year he’d really have nothing to take at the HS as I said, so would spend all the time at the college (other than hopefully hitting band a couple days a week). He would still be able to take Analytical Chemistry, Organic Chem 2, Calc Based Physics (as opposed to just independent study AP Physics C which is all he can do at the HS and will next year), and more math classes (Linear Algebra, Math Modeling, etc.). Also might squeeze in a Spanish class (since he’s done with that as well) and/or an English class (ditto) depending on how the schedule worked out. </p>
<p>But…most likely those classes wouldn’t transfer very well to MIT’s standards. My older son is currently taking Diff. Eqns at the same college and after having sat in on a class during CPW isn’t even going to try to transfer the credits since he doesn’t think the class is anywhere near the same caliber. However, if for some reason younger son decides to head to Wisconsin or a state school, he could easily transfer enough credits (between the college classes and the 11 AP’s) to probably start as a junior! Hence the reason we wouldn’t just graduate him a year early without a solid plan/acceptance - if the state is willing to pay for that year I’d rather have them pay than me! </p>
<p>So, thanks for your help - but how would this affect things? Oh, and he’d still be entering at 17 (spring birthday) if he went after junior year, not 13. 
I also believe that since he’s been taking classes at the HS since he was 11 (and starting in Sept at the college at 16), I don’t think he’d have a problem with the maturity part of it. Thanks again!</p>
