I use CTY for math. It is organized, suits my needs.

Though I found that they do geometry online for the course. They use a button and get a perpendicular line, but on the exam, they need to use a compass and protractor. You have to help them learn these things.

That would be the same for both since Epgy is CTY basic. CTY does have many other courses I am interested in down the road and their camps.
