We've been very happy with this program and the results! Our twins will be starting kindergarten in the fall but because we have been traveling for the past 3 years they have not received any formal pre-k education. When we got the program they already knew the letters and sounds so we whizzed through the first several lessons. We don't follow the program exactly as written because we don't have a set schedule but the results have been fantastic! They love reading the books and have set their own goal to finish all the levels by the end of the summer. It's a bit ambitious but I think we can do it! thanks for the support!
