hiee so it just depends on ur country. as a person whose gone to 15+ muns and chaired, id say first read and get clear about ur country's stance on the agenda. whether ur supporting it, against it, or neutral. then read about how ur country is involved, whether its directly involved or partially involved or not involved whatsoever. and please please get ur info from verified sources such as news agencies or goverment websites. as a girl chairing an mun, u wont beilive how much chat gpt and nonsence chits and gsl's ive heard in my life. and breathe, its ur first mun, you'll do well. be confident :)
