Physics is really a working knowledge, like computer programming. You have to be able to solve problems. All the 'practical' and 'intuitive' aspects of theoretical physics are built by working on problem sheets. A lot of progress in understanding (both personally and for the field!) is in tackling apparent paradoxes.

Susskind's courses are very much overviews / appreciations. For each of these areas (GR, StatMech, Quantum etc.) you would expect several 30-hr lecturer courses + problem sheets (or equivalent working through a textbook) to gain a deep knowledge.
