Students who earn a satisfactory score on 9 problem sets (i.e., programming assignments) and a final project are eligible for a certificate. This is a self-paced course–you may take CS50x on your own schedule.

They were not kidding when they said the course was "demanding". I spent at least 2 hours daily working on the course and each course week took me a month to complete. It was exhausting a lot of the time. The problem sets are designed in such a way that one is forced to read and do further research to accomplish them. The sense of satisfaction I gained from completing each problem set was tremendous and even though the learning curve is steep (to say the least), I am now comfortable in my understanding of the basics of computer science and in coding in C. The web design module was probably the most fun even though for me personally it was the most demanding.
I guarantee you will be pulling your hair out sometimes if you take this course, but you will have tremendous fun most of the time and the sense of accomplishment is exhilarating!

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.
Because the course was hard. The homework assignments, which were offered via the same appliance that the live students used and submitted to the same grading tool as well, took me anywhere from four to twelve hours apiece.

CS50x is essentially like taking a real, full-length college-level course, complete with lectures, breakout sections, walkthroughs, homework, quizzes, etc...
Prepare to be infuriated after watching 5-6 hours of video content and realizing that you still have absolutely no idea how to actually do the homework. If you're looking for somebody to hold your hand through the syntax (like the 56% of people with no background in CS likely were), you won't find it here.
I’m having a hard time describing CS50 without sounding hyperbolic. The course was just so damn good. The content is engaging. David Malan is too good at his job. The production value is absurd. Honestly, go check out a lecture for the production value alone.
I have now completed CS50, Stanford CS101, and half of Udacity CS101 and without question Harvard’s introduction to computer science is my favourite.

A lot of effort can be seen to be placed in the production of lectures/shorts, making it very enjoyable and the concepts understandable. However, if you already know the concepts, the videos can seem overly-theatrical.

There is a lot of good stuff here, but is is so painfully disorganized it is a chore to figure out. Navigating the dozen sites associated with the class is more difficult than the actual material. If they ever organized this, it could be good. It is like they are trying to waste as much student time as possible for very basic instruction.
This course felt like a full college course. It is the first MOOC for which I felt like I would really have earned 3 or 4 credit hours because- similar to taking it in-person. The instructor, David Malin, does an outstanding job of making it interesting as well as making it easy to submit problem sets and get them graded quickly (because it's mostly automatic). There are lots of people taking the course at any one time so the Facebook group is very active with people helping each other.
this is such a great course with soo much info around, which is really easy to find via the courses own website! a lot of seminars, older courses and david malan and his staff are doing a great job teaching ppl, who didn't have any cs experience beforehand! the learning curve is steep but doable and there is a lot of help out there! great staff and great community!!!
I am currently taking MIT's python course. It is designed much better for beginners. While lectures for CS50 are phenomenal, problem sets are not realistic and quite discouraging. I am glad I decided to try something else.

The introduction to Computer Science course from Harvard University CS50's was amazing. The course was delivered in a timely manner. The material and resources used were excellent. The facilitator did an exceptionally great lecture series which was easily understand. I can now used this wealth of knowledge and expertise in teaching my students better. This was a very informative and great course. Great job.
I thought this was a great introduction to computer science. The instructor David Malan is one of the most charismatic instructors I've ever seen. The team behind this course did a phenomenal job in creating an extremely thought out curriculum with challenging and interesting problem sets. This is not an easy course but was well worth the effort.
Hannes is taking this course right now, spending 1 hours a week on it and found the course difficulty to be medium.
Although I've only just begun, and don't necessarily plan to finish it at once, I may well end up doing so. Fun and engaging lectures that takes you along the way, step by step. This will be helpful for me in the future.
