The curriculum, identical to that of the classroom MIT course, was challenging. Spanning almost the entirety of the 1000-page course textbook, which Agarwal coauthored, each of the 14 weeks of class included 2 to 4 hours of lectures, online exercises interspersed with lecture sequences, a homework problem set, and an online lab, which involved building and testing simulated circuits. Optional video tutorials supplemented the lectures with solved problems and math refreshers. Midterm and final examinations rounded out the busy calendar. The problem sets, while self marking, tended to escalate in difficulty. One entered an answer, clicked on the 'check' button, and after a pregnant pause, the grading software delivered a scarlet letter X or a green check mark. Of the original citysize class population, 5800 passed the final exam, and 7157 earned enough credit overall to pass the course and receive a certificate of completion.
