In the first tutorial I genuinely thought I had made an administrative mistake and entered a class for people who already had law degrees. Everybody seemed to have an argument ready. They could refer to the text without looking for the page. I had read everything, but the moment somebody asked what I thought, my brain offered absolutely nothing. For a few weeks I treated every confident answer as proof that I was behind. Then I started noticing the pauses, the tabs open under the table, and the way people repeated each other with slightly different wording. Some people really were very prepared. Some were simply more comfortable speaking before their thoughts were finished. I am still learning how to do that. What helped was preparing one question rather than trying to predict the whole discussion. A question gives me somewhere to enter. Once I have spoken once, the second time is easier. I wish somebody had told us that PBL is not only learning the material. It is also learning how to be visibly uncertain in front of other people.
