Scientific one?
Absolutely not.
Also, imho your view is very US centric where quality of education seems very low even in allegedly good colleges. I have been an exchange student at OSU (some other friends went to more ivy league for their ones) and we all found the exams just...insanely easy.
I couldn't believe people would not pass exams, not only it was overwhelmingly multi choice exams, but professors would even grade you based on assignments and would post "example exams" days before the tests.
I really lost a lot of respect for US universities based on my and my colleagues experience.
I know and I hope some places have it tougher, but even people at MIT or UCLA told me similar stories.
In Italy for comparison you needed to know from A to Z and would have to do exams again if you didn't know anything.
Which is obvious!? How can you build bridges if you can barely scrap Calculus 1 or 2. Insane.
