We actually had this exact thing at my university. One sophomore level weed out class was a "self paced" electrical engineering class. It was called self paced because you were given a textbook and were free to work through it at your own pace. But to finish the class by the end of the semester you had to average 2 chapters completed per week, and completing a chapter not only included finishing a problem set and taking a test which you had to score 90%+ on (and were required to finish another problem set and retake it otherwise), but on occasion also demoing some skill in the lab.
It was brutal, but one of the most educational classes I've ever taken - and obviously not just because of what I learned about electrical engineering. Of course it seems modern universities have just become profit-driven degree treadmills. Weeding out students? That's reducing profit! And yeah looking back at my uni's page it seems this class is no longer self paced. Lol. And that's at a top 10 school. The enshittification of education.
