That's not really the point of the lectures. They are meant to be used as a supplementary material.

If you are learning physics fo rthe first time, I would highly recommend Walter Lewin's video course, also available for free:

EDIT: I should say also that an actual textbook with exercises & problems is required for anyone learning physics. There are many to choose from: I used Halliday, Resnick and Krane's. The lab component of a physics course is also essential, but sadly I don't know how to replicate that at home. You get a small portion of the benefit from watching Walter Lewin's lectures, as he does many live physical demonstrations, but that's not the same as doing the experiment yourself (and learning about experimental error and from the mistakes you make).
