My entire Differential Geometry course was based upon this book so I relented and splashed out a bit to get myself my own copy that I can annotate freely. I bought a second hand copy for ~£52 and it came in perfect condition. My seller was kind enough to wrap it tightly in plastic to prevent any damage during transport and the pages were not marked or damaged at all.<br><br>I personally really enjoy the way this text has been written there's enough detail in the theory to the point were it satisfies me as reader but not so much repetition that it becomes drab. Concise, detailed and thorough in the theorems and proofs presented. Enough exercises to satisfy the passing reader but I guess you can always wish for more :D Hopefully those will get supplemented by your professor. But as always with most graduate student books they are there as a detailed 'dictionary' if you will - not so much as an exercise book.<br><br>If you want something that covers all bases in your beginners quest of Differential Geometry this is the book for you!
