I was very suspicious of this program because everyone says that their kids are doing so well after struggling with other programs. It made me wonder if TT is just too easy. So, after looking at the online samples (which were VERY simple and basic) I have determined that TT is not challenging enough for a college-bound math student. I'm probably bursting some bubbles, but you have to honestly ask yourself why your student is all of a sudden having such an easy time with Algebra.
