I am one of many poor college students looking to save some money this upcoming academic year and I am thinking of buying international versions of my textbooks. Specifically, Classical Mechanics by Robert Taylor Optics by Eugene Hecht I was wondering if anyone knew in general the differences between international textbooks and their us printed versions. I am hoping to hear some first hand experience of people who've taken this route. It worries me that some of the problems might be different which would be significant in my courses. I appreciate your help! Thank you!
