In my experience at US universities, our course grades were determined by 2-3 midterm exams and a final exam. A common weighting scheme was 3 x 20% for the midterms and 40% for the final exams. Sometimes they had 10% weight for homework, labs, projects. There were some courses where there was a final exam but the rest as projects, papers and presentations.
