<p>MUN varies greatly from school to school. One of my kids participated freshman year in the Nashville area and went to a conference right in Nashville - day trip. Her prep work was minimal and it seemed like a very unlikely solution to a major world issue. When we moved to Shanghai, China the school there had a much more serious commitment to MUN and participated in several conferences - from city-wide to international - with resolutions picked to be presented at the actual United Nations. The kids who participated were well informed and excellent debaters.</p>
