We are trying out OM for our 2nd grader this year. I went to the virtual info session and they said that the online school isn't really online, meaning you are not interacting with other teachers or students in a virtual setting. You are simply handing in assignments for teachers to review and give feedback on. I was told this option is really better for older kids who need to be held accountable for their work, and isn't really that necessary for younger kids, which is why we chose the curriculum only option.
