In the framework of the Hungarian Science Day, our lab organised a hybrid workshop entitled "Educational Data Science: mathematical answers from the educational administrative system". During the workshop, the audience had the opportunity to learn about our latest results in four presentations and get answers to the following questions:

• Is the Hungarian admission scoring system fair? (Roland Molontay)
• Is it possible to predict university drop-out rates based on the data at the time of admission? (Marcell Nagy)
• What is the value of mathematics remediation at university? (Baranyi Máté)
• Can professors buy student evaluation with lenient grading? (Berezvai Zombor)
