From Our Learners

  • “Excellent course! Very insightful and helped me to verbalize the details of my teaching philosophy. Leaders of Learning is a great course for each and every individual to pursue. If you are interested in learning, teaching or leading, join this course.”

    - Prashant

  • CS50 turned out to be precisely what I wanted. The platform is reliable, the UX is crisp, and, most importantly, the course content is phenomenal. Professor David Malan and his army of TAs put an absurd amount of effort into giving Intro to Computer Science actual LIFE. From the first video, it inspired that nervous excitement that always accompanied my setting foot into a lecture hall for the first time. This wasn't YouTube, this was the Real Deal.”

    - Erik

  • “This series of courses on China (ChinaX) is one of the best classes I've ever taken, in my entire academic life. Extremely interesting, very thought provoking, and taught by instructors who are extremely enthusiastic about the topic.”
