Thanks, Cathy. So far EPGY 3 is all review of the CTY problem solving course. Nothing new yet, and he's up to 3.25. I didn't realize it's a 3/4 course (like EPGY LAW which is 3-6). I guess he may as well finish it and we'll look to supplement next year. So I'll ask about Singapore and Aleks, and I suppose continuing in EPGY, which I'm sure they won't allow.
