MUN conferences are time consuming. Often the topic area of discussion is complicated and hard to solve or reach an agreement. For delegates to keep their minds sharp and clear, a MUN conference is divided into several sessions, each taking about three hours. One session can be seen as a time unit for a conference period. After continual sessions of discussion on the committee topic, delegates will have heard from all viewpoints the different dimensions of the issue. WorldMUN usually holds six sessions in each committee.
