I finished my bachelor's less than 10 years ago and it was still the case you could easily flunk out (more than half of my cohort did in first year), exams were worth 90% of the total grade etc. However, this is just not the case for EDUCATION degrees and this is a big part of the problem. They have been notoriously easy for decades.

But don't worry, teachers won't be able to teach from books for long, because new school curricula are trying to bring an end to all that literacy. You can just play videos instead of lessons after all.
