Mathematics tools

I would like to hear from K-12 math teachers in the US who are using Moodle to prepare their students for high-stakes tests, including

• SAT and ACT (college entrance exams)
  
• Advanced Placement (AP) exams
  
• State-specific tests mandated under No Child Left Behind (NCLB)

I am especially interested in the NCLB tests and how we can use Moodle to raise the scores of students who are in danger of failing.

I have done a lot of work in this area, and I will be glad to share my ideas and experiences with you. Thanks!
