Currently there appears to be no way to go review ESRI Academy course content without staring the course over. These courses have great content and often provide information that is helpful when trying to find supporting documents on an ESRI product.
With that in mind, there seems to always be something I would like to review, but I really don't want to run back through the entire course, just to look back at one thing.
Please consider an option to review completed course content without having to start over.
