We love Mathnasium and what is more important to us is that our 10-year old daughter loves it. Initially we were just enrolling for the summer (May-Aug) but we've kept her in because we see the benefit of the program. Love it!
I understand that Mathnasium is not a tutoring service, but a teaching service and that is what I appreciate. They are not trying to cram information for the sakes of passing a test. Mathnasium teaches math. A child does not fail overnight, therefore it takes time to recover from failing grades.
