I took 61A with Hilfinger (who usually taught 61B) and I didn't crack the book. His lectures and notes were very thorough. I can't remember if there were readings on the syllabus that I skipped but I didn't crack the book. Moreover, I was always big on doing the reading before class. Class was a review.
Later when I did read SICP, I didn't like it. Maybe that was like reading the book after seeing the movie. Dunno, but I didn't like it.
As an aside, there was a whole subculture of students who read nothing but just did the HW and worked past tests and sets. They did amazingly well. I had a study buddy who did that in EE20. I prepped him for the final and he told me he'd beat me; he narrowly did. He graduated with a 3.9+ GPA in EECS which is insane. He hated ideas then and now. But he tested insanely well. It was just pattern matching.
