I will probably post a more detailed review on my blog but can I just say that I LOVE this program. We have struggled to find something that worked well for us. I love parts of MUS but now (4th grade) feel like somethings were missing and we were struggling with feeling behind. So I signed up for a trial of ALEKS.com and G is loving it. He is doing great and at the rate he is going he will finish the 4th grade work right on time.
