5. Repeat Step 3 and Step 4 three more times, choosing different letters so that you ask different students each time. Then if you have students in the teams who have not yet answered questions, quickly renumber the questions and repeat Step 3 and Step 4 as many times as you need until everyone has answered a question. If you have a team with fewer students than another team, ask them one or more extra questions so that all the teams are asked the same number of questions.
