Kriston, I couldn't help but smile at your card-carrying feminist comment.  I loved sports, too (varsity letters through high school and college in four different sports - that shows my age, LOL, they don't allow that anymore..).  Oh, and if it hasn't been mentioned earlier, I'm the mom, not the dad. 
Re: my earlier posts, DS complained succinctly on the way home today about his new school compared to his old.  At the old school:
1.  "The classroom was quiet."
2.  "They didn't teach me things I already know."  
Finally, Texas Summer, thanks for the info.  I signed him up and paid for CTY and EPGY before I knew about Aleks.  And frankly, the move from private to public school made those courses seem like a bargain.  But they are expensive.  Good to know there are other options, and that there's no problem using what we're using.  Thanks for the reassurance.
