The official manual, obtained from cambridge.org -- this is not the same as https://www.cambridge.org/us/academic/subjects/physics/cosmology-relativity-and-gravitation/students-manual-first-course-general-relativity
The current manual's answers are much more concise; each occasionally contains solutions to problems that are absent in the other.
