Quizzes
Quizzes are 20 minutes long interactive conversations with the CS50 Duck, course’s AI-based software, with the goal to reinforce lecture’s concepts before you jump in hands-on activities during sections. Quizzes are graded based on completion and are due before you arrive to your assigned section time.
In Gradescope, the assignments’ deadlines are always shown in Eastern Time (U.S.).
