I am an undergraduate student in Electrical engineering in Purdue University and i bought this book a few weeks back. Although this book advertises itself as 'Super reading', but I think the title maybe more apt if it was 'Super Skimming and Test Question Spotting.' I do admit that skimming is one of the techniques the author discussed in his book, but those techniques are,in my opinion, only valid when: 1. You want to pass the exam ONLY, OR 2. You are reading for fun. With regard to reading technical stuff. I just tried the techniques he offered but all in vain. Technical, 'dry' materials cannot be learnt that way. Moreover even you manage to pass the exams by guessing/spotting questions, you land yourself on a very shakky ground when you do higher level course work since all those courses do depend on the material from previous courses.(And the lecturers expect you know the materials in the courses you have taken, even they were not tested in the exams.) So, Mr. Berg's 'superb' achievement by learning a subject in 7 hours, spotting the questions, ignoring materials he thought wouldn't be tested and got a B+ in that exam totally defeated the purpose of an examination. My final advice: Save your money.
