Which colleges are known for having the harshest grading systems?

I've heard that the grading system at some universities can be notoriously tough and I'm wondering which ones are known for this? More than just the difficulty level of coursework, I'm interested in understanding how colleges differ in their grading policies, marking schemes or curve systems. All insights would be hugely appreciated!

Sure, I can provide some insight into this. A number of highly reputable schools are often mentioned when discussing strict or challenging grading systems.

1. Princeton University: Though it loosened its notoriously strict grading policies somewhat in 2014, it is still known for its rigorous standards. The university previously had a policy that limited the number of A-range grades that each department could award.

2. Massachusetts Institute of Technology (MIT): MIT is notorious for a tough grading policy. While incoming classes typically have almost all straight-A high school students, the school's challenging STEM-focussed curriculum and steep grading curve often results in these same students earning lower grades than they were accustomed to in high school.

3. University of California - Berkeley: UCB has been deemed an academically-challenging school, with some students finding grading practices quite severe, particularly in courses offered by the College of Letters and Science.

4. Reed College: This liberal arts institution is known for giving tough grades. The school emphasizes independent study and a high degree of academic rigor.

Please note that grading policies do differ widely among faculty within the schools, so it's important not to generalize too broadly. Moreover, while these universities might have harsher grading systems, they also have a reputation for providing a phenomenal education that equips students with strong critical-thinking skills, making their graduates highly sought-after in the job market. Remember, challenging coursework and rigorous grading standards can be an important part of the learning process, helping you to push your own boundaries and improve your academic skills.
