I'm not sure if this is the right board to post this on and if it's not, let me know and I will delete the post myself. What is the points of grades, you either know perfectly the subject or you don't. What is the point of education if you can just know half of it, and then you will also continue pretending to learn even more advanced stuff even though you barely know the basics? Isn't this very anti-scientific and anti-productive to a civilized society?
