Open School courses are asynchronous, in that you independently work on the course content on your own at any time. You will have access to videos, worked out sample questions, and multiple formative practice questions to help you grasp the concepts. If you run into issues, your instructor is just an email away (you will have direct contact with the instructor)! It is like having a built-in tutor for the entire course. Your instructor will provide you targeted assistance in video, audio, or written form to help you get back on track.
