-1. Briefly introduce yourself to your pair (name / academic program).
-1. On your own, answer the following questions (yes / no):
-    a. Did you have any experience using Git before this class? (y = 1 / n = 0)
-    b. Have you ever used a shared GitHub repo for a collaborative project? (y =
-      1 / n = 0)
-    c. Have you ever fixed a merge conflict? If you're not sure, you
-      can answer "no". (y = 2 / n = 0)
-1. Tally your answers using the values I gave for each question so that you get
-   a number between 0 and 4. (_NB: Your score carries NO judgment. After this
-   course, each and every one of you will have a 4._)
-1. Show your total to your pair. 
-    a. If you both have 0 or you both have 3 or above, please **raise your hands
-      and keep them raised**. Don't worry, the class will assume you have >= 3!
-    b. Otherwise, move on to the next section.
