About serlo.org
Serlo.org offers intuitive explanations, courses, videos, exercises and sample solutions. Students can use these to learn according to their needs and at their own pace. The entire offer is completely free of charge and advertising. Serlo.org is made possible through authors, software developers and project managers, who are inspired by our vision to make high quality education easily accessible to everyone. We are eager to offer students the opportunity to learn autonomously. Together we are building the Wikipedia for Learning.
