Cornerstone helps home school parents of older kids with subjects they may struggle to teach. Some courses offered are Algebra, Geometry, Biology, Physical Science, & more.
Each "course" is more like a group tutorial for the home school kids. They meet once or twice a week, and are given "assigments" in the meantime. But much of the learning & homework still takes place at home. The Co-Op classes just give kids a place to ask questions, and participate in hands-on activities (such as disection & science experiments).
