One more reminder: On Tuesday you will have your final assessed seminar discussion.This time you will talk about the case studies that you can find on p. 59 in your booklet. You will need to prepare for ALL the case studies as you will be expected to discuss all of them. I found these video links where you can watch sample seminar discussions:
