Wasn't the case for me. We had several courses that were team efforts, and the typical method was to determine a shared team score, and then let individual scores deviate by a small margin (+- 2/20 at most) from that, based on the professor's appreciation of your individual contribution in the team.
Exams made up part of our marks, but projects factored in as well. One could certainly achieve a passing grade while being a terrible team-player, but it generally was not a successful strategy.
I'm currently getting a software engineering degree and I got multiple class where we had 50% of graded teamwork and you needed to pass them to be able to pass the class. Even if you got 100% in your exam, if you failed your teamwork, then you fail the class.
