The bachelor in Economics and Business Administration at Aarhus is prerty demanding but it is not a super aggressive, competitive vibe. You can expect a full‑time workload with quite a lot of reading, group work and assignments during the semester, not just before exams.
generally the atmosphere is friendly and pretty relaxed. People work hard but you mostly cooperate in study groups instead of competing with each other all the time. TLDR it is serious and you need to stay on top of things but the social and study environment is supportive.
