CS61A was great when they taught via LISP (Scheme). Have they switched to Python? Probably still good but would be nice to have LISP.
The book is amazing, but it is also very extensive/overwhelming and I found that the lectures provide a better guiding structure for myself and the lecturers are also quite entertaining at times. The website also provides additional material related to the course such as exams, projects and lecture notes.
