For high school students, passing the state matura exam requires a lot of hard work and studying. In this thesis it has been developed a web application which will through an interactive and interesting way help students to prepare themselves as best as possible for their matura state exam. Main feature of this application is updating the question database and generating new patterns by the administrator without needing to change the application code. Latest technologies, required for making this type of application, were used during this application's development. All of those technologies, with an emphasis on Action Script 3.0 programming language, are described in theoretical part of the thesis. From this programming language online forms and question will be retrieved and generated in the quiz. Furthermore, development enviroment required for making this type of application, is specified. The whole procedure of application's development, from idea to distribution, is explained in the experimental part of thesis. However, before creating web application itself, application market had been explored in search for similar web or mobile applications that could also help students with preparing and learning for the state matura exams. Found applications were analyzed and mutually compared, their pros and cons were described, and results of research have been used in the process of designing user interface and other funcionalities of the application.
