Q: In the video, the speaker mentions summaries of the video lectures. Where do I find the summaries?

A: The summaries are at the end of the videos. So, they aren't kept somewhere in Magoosh; they are within the videos, at the end.

You can scroll to the end until you see the words "Summary" in bold. It should only take a few seconds to scroll through to the end of the lessons.

For example, in the lesson above, the summary starts just after 7:30. In the lesson Positive and Negative Numbers, it's at about 7:25.

By the way, you can also see the lesson transcript by clicking "show transcript" below the volume button.
