Okay, so I found one of my books I need for school on Amazon:
Introductory Circuit Analysis: Amazon.ca: Robert L. Boylestad: Books
I can get it used for $138.42, which is disgustingly expensive for a used copy. However, I found the international edition of the book on ebay for like $39
Introductory Circuit Analysis by Robert L. Boylestad (2010, Other, Mixed... | eBay
Most people say the two books are the same, but for an engineering course, the units of the problems need to match that of the instructors. Now, I assume because it is 'international' they will be using the metric system (the same one that Canada uses) but I'm afraid the problem sets might be different. Can anyone testify their experience with the international edition of books?
