Polish Nationwide Mathematical Student Conference OMatKo!!! was set up by students from all four mathematical scientific clubs at Wroclaw University of Science and Technology. The fifth edition of our conference took place from 13th to 15th of April 2018 and it has become the biggest mathematical student conference in the whole country, attracting more than 200 students. There are both Polish and foreign students among our participants. This event is dedicated not only to mathematics and informatics but also scientific related students. Our project gives an opportunity to gain knowledge and share experience, as well as to develop soft skills and public appearance among both participants and the organizing team. These actions contribute to young people self-development and push to cooperate with others - the conference enables participants to establish cooperation between active students and we encourage the most outstanding individuals to constant improvement.
