We run the session similar to a pub quiz, reading questions from a book. We separate into 2 or 3 teams, depending on attendance. We welcome new members - and we could have more teams if we got more members. One of the group acts as question master and each team writes down their answers. The answer sheets are then exchanged for marking. The group is informal and we have a lot of laughs as we are not genii. (Plural of genius?)
