When did you take it? I have been wondering about this, as well.
I was told by quite a few people that it DOESN'T include most of their techniques, was mainly practice questions from past LSATS and that you could only get the techniques in class--a former instructor told me that and at least 2 or 3 people who took the class told me that. I don't know when the instructor taught there, but I think the people who told me that had the newer Testmasters books (the blue books vs the ones that look like notebooks).
I was told they don't include their techniques in their book because Robin Singh, Testmasters's creator, doesn't want their techniques getting out.
