We have tried other grammar programs but my son asked for this one back! He has high functioning autism and learns best in small increments of information repeated frequently. He remembers all the "rules" with the songs. The lessons are short enough for him to focus. He is in the 5th grade. This is the third year we have used it.
I think is would be way too advanced for a learner who struggles more or even an average learner. This is for a very self motivated and advanced learner and for one who isn't into very much flash. Meaning the book doesn't grab a young childs attention as wow I want to open that up and learn.
I like teaching this program. It is much easier than Abekka which we found hard to use and understand. It is not a favorite of my children who are 11 and 12. They find it repetitive and they say too kid like. The jingles just need some life. We didn't use the cd just because all the lady does is just say the jingles. We rapped them! It did make them easier to remember. It is a good program. :)
We homeschool & are currently using this program for our 5th grade daughter. It is very thorough, explains things well (for the most part), and incorporates writing as well as grammar. In my opinion, some of the lessons are long so we split them into two lessons. As with any program, I tweak to suit our family's needs, but all in all I believe this is a well rounded curriculum. It is our first year to use it, but I plan to order it again for next year.
