The CTY Camp was great for my 5th grader, but there is a bit of a trick. You don't want to take a class on something you already know a lot about because these are still meant to be introductory classes. So if your child's passion is ancient history and they read everything they can find on the subject, then it is likely not to be the best class. Instead, have them take engineering that they are intrigued by, but probably wouldn't pursue on their own. This gives them a chance to open their eyes to other subjects in a fun and faster pace than a school might allow.
I've noticed when people pursue their passions at CTY, they are often disappointed. But, when they try something new they seem happier. So, when dd took the class we followed an interest in life science...but side stepped over a bit to pursue a science not previously studied. The science also had a lab every day, which was a huge hit with dd.
