Engineering at my EU uni, homework and coursework were at most a tiny part of the total grade, and never enough on their own to pass. If they were relatively bigger projects, you'll pass an interview or similar review after delivering it. This all were just nudges study and to check ourselves and they were seen as a "gift" of the Bologne Process (restructuring/standardizing of unis in the EU).

The only thing that mattered were the exams, be it pen and paper or coding/electronics labs, in person and proctored. No matter how much slop I could have access to back in the day I would have failed the same subjects I did.
