This is the sixth lecture in the lecture series that is available for sale. You can choose to purchase these lectures in audio or video formats through our store. But the least expensive way to hear the lectures is to access them from inside this online course.
The first six lectures are free so you can see the quality of what we are offering, but beginning with chapter 6 you will need to purchase the lectures if you want to have access to them. Go to Chapter 6 and click on the "Purchase access to the audio and video lectures" link (or you can go directly to the store). You will be taken through PayPal where you can purchase the lectures. Once purchased, you can continue to access the lectures from inside the online course, just as you have been accessing the free lectures.
These lectures cover the entire chapter. The Chapter Overview lectures, also included in the online course, summarize just the high points of the lecture.
