Classes are offered in two formats: In an online classroom, you will be able to join live classes using an app that allows you to interact with your teacher and other students in real time. Attending live online classes requires a computer or tablet that is connected to the Internet, with a webcam, microphone, and speaker. Pre-recorded classes are videos you can rewind, fast forward, and watch as many times as you like while they are on the internet with your current, active subscription.
