Coursera courses are 6 to 10 weeks long, with an hour or two of videos per week. In addition to the snap quizzes, they feature weekly exercises, ranging from problem sets to spreadsheets to design projects or essays, and sometimes a final project or exam. For all quantitative courses, the platform uses artificial intelligence to evaluate each longer exercise, with instant results. Students can keep trying until they get the right answer. For humanities courses, Coursera is testing a form of peer grading.
