Hi al_godnessmary,
Thanks for your question, and congrats on reaching the 170's! First of all, I must correct your observation that test review is somewhat "inactive." It's not... or at least it shouldn't be! It requires actively re-engaging the questions, ideally by doing them all over again. The key is to reach the correct answer choice on your own, rather than buy into whatever answer they gave you as correct. Then, write a brief explanation explaining to yourself why you missed the question, and what you should have done differently. Check out
