Today, I talked to some of the math team members, in preparation for Criterion K. 
They said they had been using the site, and offered these comments:
-Well organized (separated into meets, events, with years for practice tests)
-Likes the summary of all equations, vocabulary 
-And the practice tests which separate into years 
-Likes the solved problems (work shown) 
- Easy to use 
-Good navigation.
They also mentioned it was now much easier to study.
