I built an online course to help students self-study for AP exams. The idea was to build extremely high-quality courses for AP exams and then create amazing tools/assessments which would allow students to self-study for the exams. One of my signature tools was an adaptive assessment tool that would tell students when they're ready to take the exam. If the student wasn't ready then they would get a mixture of lectures, videos and small assessments to teach them the concepts needed to pass the exam. I eventually closed the service down because the reality is the edtech market for these type of products is very small.
