I do agree with you there. I thought last summer's Algebra I 5-week class was a bit too fast. He got a lot out of it though, and he aced his CC 2/3 class last year. He took the SAT last year as a 7th grader and did really well on it, qualifying for TIP.
He's acing the 5-week geometry class this summer. I was thinking of asking the school if he could take a Geometry readiness test, if they have that.
I had not thought of asking to skip next year's math but the summer Geometry teacher, who teaches CC math at a high school, suggested it.
If it would be a good idea for him, he could then in high school take either 3 AP math classes (AB and BC calculus, AP statistics), or his senior year take college math at our local university (not a community college).
