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.
