Damn America has tough grading rules. Most schools in Sweden have C 50%, B 75%, A 85-90%.
75% for C? fuck that shit (we don't have D)
It's inconsistent, actually. When I was in college, grades varied from professor to professor.
My physics professor, for instance, did not give partial credit. A problem was either correct or it wasn't (Makes sense TBH, since if you get the physics correct, the math falls into place.). There were five quizzes, a midterm, and a final. You could drop your lowest score of the 5 quizzes, though. Each quiz had 3 problems and the midterms/finals had 6-8. You could drop your lowest scoring quiz (and there was homework, too, though it accounted for something like 10-20% of your overall grade)
The grading scales for the physics courses of course adjusted with the difficulty of the problems and the overall class performance (They were honors classes of ~80-100 students), and you weren't generally expected to ace an exam (His logic was that if you design an exam that is easy enough for a student to get 100% on, you can't gauge the depth of their true understanding... they could understand the material 10x as much as another student who got 100%, for instance. The limits of their understanding would be unknown.).
There were a few times I got a 0 on a quiz in the multiple semesters I had him as a professor. Definitely wrecked me for a bit, but I persevered.
Great teacher, hilarious guy, although his jokes could get a little cringe-worthy at times XD
