Examination copy is the teacher review copy. It almost always has the same exact contet. It is not better it is usually the same. If it is cheaper I would say only then would it be better.What is the difference between an examination textbook and a regular textbook?
It's the same thing. It's just that it was a copy initially issued to a professor for him or her to review and decide if he or she wants to use that book in his or her classes. The only thing about it is you can't sell it back to the bookstore.
