"The A.I is brilliant, the comments are perfectly pitched for ages 7+.

With Synthesis, I get to see that almost every time. Even better, I am starting to see them applying strategies they learn in Synthesis to other topics." - Parent of Maggie (12) and Mike (9) "One of my son's passions was always math, but lately he was less interested because he said his math class was too easy and boring.
