It's much better then the book my school supplied, 'Physics 1', and as such my teachers refuse to teach from it and instead ask questions from this book.

Despite the fact that no-one seems to have proof read unit 10.2, which has a table with misaligned data and a diagram with no measurements (which a question then asks about), and that questions that require full sentence answers don't have answers in the back, without it I'd be completely lost in Physics. I can't recommend it enough.
