For maths and physics lectures, I always got vastly more out of them if I could somehow obtain a summary beforehand and be conscientious enough to read it through. (Similarly, I found the best way to read the Feynman Physics lectures was to read through the published text, then listen to the audio recordings while reading the text. You can do the same with Leonard Susskind's Theoretical Minimum physics lectures).
