Thank you all!
Sorry to all for the long delay! We are leaning towards Comp Sci. He might do the CTY C++ over the summer, just in case the AP (in Java) is too rigorous during school year...he just wants to get as high a grade in AP exam as possible (no complaints on my part!) I'm meeting with the school next week to finalize. The thing that worries me is that, he wanted to do pre-calc over the summmer, and start Calc in the fall. Both, school teachers and myself, decided that was just too fast; instead, he will do a 1 year 8th-9th grade Pre-Calc w/ Trig (Saxon). Not thrilled about being with older kids, but what can you do?
delbows, thank you for your kind words, it is an AZ charter school.
austin, lilmick; he has not read Euclid's Elements , but done geometry. Right now, for the near future (after AP Calculus BC), the best I can find is Stanford's EPGY math courses (undergraduate level) since it's the best chance at not having to repeat all his coursework in high school and/or college? Any suggestions/recommendations are always welcome!
Both the school and I are working at getting some local university professors on board. I've introduced him to several math phd's the last year and a half or so, and he was lucky to be invited to help in an NSF grant project with UIC! It seems math will take him places. :-)
Thank you all again!
