Hi Walkington,
My dd really liked CTY science last year. I was going to sign her up for summer again this year but the class she wanted to take (Robotics) is for 5/6 graders and my dd is in 4th for homeroom.
Even though this is considered a math course; they only require 5th grade math; and my daughter is already doing Algebra, they would not do a grade exception because of her age. There wasn't another class she wanted to take at CTY so she decided that SIG would be more fun.
Overall, CTY was very good for my dd last year. We may go back next year when she qualifies for Robotics if she still wants to do it.
