It's high school- and college-level material. I haven't used any of it with my DS8 yet, but he is very visual, so I'm hoping to crack out some of the math to supplement/reinforce what we're doing.

Frankly, I have a hard time not buying from TTC for *me*! I don't mean to sound like a commercial, but their course descriptions are so intriguing. The "I want to major in everything" college student that I once was gets all excited! laugh
