Practice the questions. Not many questions will be taken up in class, if any at all. Do the work and compare with others, and ask the questions your friends can’t answer. Theory will not be spelled out for you. You have to make those inferences yourself! Make sure you UNDERSTAND above anything, because so long as you demonstrate successful understanding he’ll give a decent grade

Always talk to the teacher if you are having difficulties. Focus on memorizing and understanding content. Lastly, you will have many opportunities to improve with assignments and papers, so don't beat yourself up if you do poorly on a test or quiz, but always make sure to follow up on things that you did poorly on because all material in this class is important if you plan on continuing with scientific study.
