I purchased an international edition for one of my classes a couple of years ago and it was slightly different, even though it had the same edition number as the textbook posted for class. It was a soft cover, all the images were in black and white, certain topics were aligned differently, and sometimes the questions in the back of the chapters were worded in a different way.
It's a tough call, as I've been burned before where I bought all the textbooks for a class and the prof. never referred to them once! :rollseyes:
Have fun in your classes!
