The Einstein Factor describes most of the techniques that are found in the Genius Code self study course. It is more of a how-to book, and this might be all you need. Most people, however, find it difficult to master PhotoReading or Image Streaming from the book alone, even though the book does describe how to do all of the techniques.
The PhotoReading self study course, for instance, includes skill building exercises designed to teach you the steps of PhotoReading and at the same time break you out some of your old habits of regular reading that might be holding you back.
In the same sense, when you listen to the Genius Code self study course, you will do the techniques along with Win Wenger. Your experience will be hands-on. And afterward, you will learn how to interpret your Image Stream, etc.
It all comes down to the type of learner you are, but most people find a more hands on, experiential approach to be more effective.
As Alex said, Direct Learning and Lucid Dreaming are additions to the Genius Code course not found in the book.
