If you click on "Browse all courses", you'll see our Courses page, and from here, you can click on the course you want to take (please be sure to scroll down to view all of your options).
Once on a specific course page, on the left side, you'll see a list of all the videos in the course. At the top of the list, you'll see a tab for the type of videos available for that course. We have two different types of videos that may be available: Lessons and Talks.
Most of the videos on our site are Lessons videos, which feature audio paired with helpful graphics. Lessons videos also include transcripts, practice quizzes, and final exams.
The quizzes are multiple-choice questions, and you can find links to them in the left-hand panel underneath each individual video's title. Final exams are available at the end of each major section.
You can find the transcript in the main content area on the right, below the embedded video. You can either read the transcript in your browser or print it to view offline.
Some courses have lecture-style Talks videos, and when they're available, you can find them in a separate tab at the top of the left-hand column.
Talks are stand-alone videos without quizzes or transcripts.
