Edgar is a web system developed at the Faculty of Electrical Engineering and Computing (University of Zagreb) for composing, conduction, and evaluation of computer written exams. As part of this work, Edgar possibilities were expanded by introducing the support for competitive programming. Competitive programming is the skill of solving precisely defined problems by writing computer programs whose execution is limited in terms of time, memory, and many other aspects. Competitive questions are defined through an adapted interface where authorized users describe the problem, list programming languages ​​in which the solution is accepted and define a number of runtime constraints that the program solution must satisfy. It is also possible to attach public or private files that will if marked as public, be available while solving the given problem. Edgar has been enabled to conduct a programming competition consisting of a set of pre-defined competitive questions that, along with other competition details, an organizer can define through the system. Competition participants are trying to maximize their score in a way that they are solving the given problems as fast and as precise as possible. During the competition, each competitor is provided with an overview of the current scoreboard, which contains information about the score, current rank in the competition, as well as the remaining time until the end of the competition.
