Large language models (LLMs) have achieved planetary popularity and have become accepted in higher education. On the basis of a survey that revealed the attitudes of students, reinforced by face-to-face interviews, and our own extensive academic background, we defined a realistic solution that enables the integration of LLMs for the creation of assignments. It embraces essay writing as well as various aspects of computer programming. The experiments were carried out during the winter semester of academic 2023/24 at two universities from two different countries. This paper unveils the experience gained in the creation of computer science assignments with and without the use of LLM. Comparative analysis refers on three approaches: traditional or manual assignment preparation without using any LLM; full reliance on LLMs; and a hybrid mode, depending on the amount of application of the LLM in the preparation of the assignments. The proposed solution was evaluated quantitatively, with the aim of becoming a benchmark for examining the integration of LLM studies into higher education. Findings reveal the importance of hybrid mode, as the most preferred approach among students.
