During the recent Covid-19 pandemic, the need for carefully selected digital self-study and learning support materials complementing regular undergraduate courses in mathematics has become apparent and highly relevant at universities worldwide. To address the corresponding demand, Magdeburg-Stendal University of Applied Sciences has established a digital Mathematics Learning Support Centre based on Moodle quizzes incorporating German-language mathematical STACK problems. This contribution presents the main motivation for the corresponding developments, our workflow along with the designated implementation and exploitation scenarios, the achievements made so far, as well as further plans.
