As others have said, ensure you get 100% on quizzes. Close to 100% on lab.
For the exam, focus on chapters that you have knowledge of. I still retain some stuff from high school days, and there were some chapters that were of interest. So I practiced those chapter tests, didn't bother about the ones that were difficult to grasp. Difficult questions in exam, use process of elimination. You will be surprised. I was.
Pro tip: If you have a high schooler in the family taking Bio, have them explain the topics to you when you are driving. Helped me.
