I like that it has so many different features for my practice, but not all are useful at this time in our training process with students. It's very helpful because we can use multiple videos from various sources as well as an interactive quiz feature which allows us to see what they know about compressions before showing them more video content or having another quiz session after seeing additional material/content. We have been able to incorporate new information into their overall knowledge base quickly without overwhelming them too much by providing tons of valuable resources right away!
