The article deals with the problem of improving the preparation of students for computer science Olympiads with the help of a specialized electronic educational resource (EER). Methodology. The research uses the analysis of existing EER to prepare for computer science Olympiads. Results. The assumption is put forward about the need to create a specialized EER for preparing students for computer science Olympiads, the requirements for it are formulated, interface and the operating procedure of EER are described. Conclusion. The use of the EER considered in the article makes it possible to increase the effectiveness of preparing students for participation in computer science Olympiads.</p>electronic learning resourcestop-down structured programmingstackqueuedequeэлектронные образовательные ресурсыструктурное программирование сверху внизстекочередьдек[Alekseev AV.
