My anatomy instructor uses basically all the same tests each semester. He has several different tests for each of his classes (micro, physio, genetics, anatomy) and they differ a little but not much. He has so many classes he doesn't really have time to make up new tests. He's the only bio teacher. I'd study your quizes, tests, and if you have end of chapter quizes in your book look over those. We also had a website in our book for pratice tests where our professor pulled questions from.
It's to your advantage that you're taking the same instructor. You know how they teach and how they lecture.
