My college classes gave a 5% weight to homework, 45% to the midterm and 50% to the final. Since I was a good test taker I could skip almost all the homework and still get an A or an A- if I didn’t do as well on one of the exams. It also didn’t help that the professors gave extremely hard exams to small classes: I distinctly remember getting a B+ on an exam where I got 1 out of 6 questions right because everyone else got half a question right. I still don’t really know quantum mechanics basics but my grades say otherwise.
