Personalized Learning

*Even though a donation is not required for full access to the rest of this site - Please help by making a donation. Thank You - R. W. Lehmann

Please help to keep this website the best that it can be. There is a tremendous amount of time and effort that has gone into creating this program, maintaining it, and hosting this site. Though I am looking for sponsors, the intention is to not make this site full of advertisements. Any donation is appreciated. Suggested donations for schools, and teachers is .35 cents per student per year. Thank You - R. W. Lehmann

*Free access can change at any time. Those who donate will be given special access and discounts in the event that access changes.
