Before buying the "book" I unfortunately didn't realize this is not the real book. Instead a third of the recording is a summary of the book's text and the rest is questions about the recording so it "helps" you study the material of the excellent original book.

The problem is that the summary text is a really simplified version of the original and the study questions are even simpler. In fact they are so stupid they are probably targeted for people well below the average IQ. I listened less than half of the first chapter before concluding it's not worth continuing. Hence will delete the whole book from my ipod.

Really wonder what student would find this useful. And can say with conviction it's completely useless for anyone else.

Will continue by enjoying the paper version of this classic.
