State Competitions in Informatics and the Supporting Online Learning and Contest Management System with Collaboration and Personalization Features MENDO

Macedonia has a tradition of organizing programming contests for high-school students as long as the tradition of IOI. In the last few years the organizer, the Computer Society of Mace- donia (CSM), used the online learning and contest management system MENDO, firstly for the organization and carrying out of the national contests, and also for the promotion of the contests, programming and algorithmic thinking. CSM tries to provide a portal for the students that will offer complete learning materials and tools, and that will motivate them and allow them to learn programming and prepare for the competitions. In this paper we will present MENDO with its new features, and we will mention some new and original features for collaboration and personaliza- tion. At the end, we will present the great improvements in sense of the number of contestants and achievements of Macedonian students at the international competitions, showing that MENDO is a valuable asset for organization of competitions.
