To attend the NMUN was such an amazing experience full of discoveries. This MUN, which is the biggest of the world, enables us to discover the UN headquarters in New York and to understand all the decision-making processes : how the vote are made ? How the negotiations are led ? How the resolutions are written ? We have the opportunity to apprehend and understand the UN mission by living it concretely.Being able to exchange our ideas with students from all around the world was an unique experience and a great way to see the world diversity.
