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.
