No one knows more about the exam you will take than your professor. These past exams are dated. Today, it is much more likely that a professor would post such questions on Canvas, email them directly to students, or provide them during a review session.
If a professor is unwilling to provide sample exam questions, she may be willing to tell students which commercially-available study aids, if any, she finds most useful.
Prof. Bob Berring recommends spending five minutes rights after each class, trying to discern the one or two most important things the professor mentioned during the class.
