On average, the video lectures run 5-6 minutes long. Rather than bundle many topics into each video lecture, we've opted to segment concepts into a large number of short videos. This facilitates quick access to specific topics within the course, and allows you to tailor the course to your particular needs.
Our course materials are abundant and they comprehensively cover each of the subjects discussed within our courses. However, we encourage you to examine the course page and to view the sample materials provided for each course. On each course page, you can peruse all of our resources to ensure that our scope of coverage is right for you.
All of our courses contain a complete series of fully-animated lectures. Beyond those, each course contains different resources depending upon the nature of the course. To see which resources are included with specific courses, head on over to our courses page and take a look for yourself.
