There are some changes on how I am going to quiz you guys. That is I decided to let you see the figures and tables from the Powerpoint file in advance so that you can prepare youself before the speaking quiz. There are 10 figures and tables in this PPT. You have to study all these 10 because I will ranromly select one of them for you on the quiz day instead of you selecting it yourself. On the speaking quiz day, each student will be called in one by one. Each student will have 2 minutes to take notes and prepare, and 2 minutes to explain the selected figure or table. In total, it will take about 4 minutes per student. Good luck for all my students, Aj. Paul
