This is not a typical computer-science class. CS50 is distinctive in another sense—more cases of academic dishonesty are reported from this course than from any other at Harvard. He said the level of plagiarism is consistent with that detected at peer institutions, such as Princeton, Berkeley, MIT, and Stanford, based on his conversations with colleagues, and has been steady within CS50 over time as well, with minor fluctuations.

As a result, course leaders added in the option to self-report the dishonesty within 72 hours of submitting the work, with the understanding that while the assignment in question might be graded zero, the matter would not be referred for further disciplinary action. In each year since then, between 1 percent and 3 percent of the class have invoked the regret clause, and in most cases the work has been zeroed.

When two submissions are very similar but there is no clear-cut evidence that the work was not done independently, Malan calls the two students in and asks them to explain their workflow in approaching the problem set. This allowed us to chat with them about issues of mental health, or academic struggles, or personal issues, so that we could then connect them with the right resources on campus.

In years prior, those students would have been completely under the radar, and that seems the worse outcome. View the discussion thread. Faculty of Arts and Sciences dean Claudine Gay sets the stage for hard choices to come. Photograph courtesy of Harvard Public Affairs and Communications.

Harvard Schools Pandemic Pressures.This course is not just made to be completed online, it is the actual course taught to Harvard students. All lectures are filmed in Harvard and put online, along with the assignments, tutorial videos and all supporting notes notes and assignments linked below if you want a peek.

Your assignments are graded, so you are held to the same standard as the actual Harvard students. All of this is, incredibly, available completely for free. The course starts from the very basics, explaining binary and using the visual, block based programming language Scratch before moving on to C.

The difficulty ramps up very quickly from there, with in depth discussions on how the computer processes the code, how information is stored in memory and what data structures are. Despite only being an intro, this course helped give me a much better idea of what a computer is doing with the code I write and address some of this self doubt I had. The course was made with a range of abilities in mind.

I still found the assignments in C quite challenging. As this course is very popular, there are also loads of other resources available like a subreddit and dedicated stackoverflow site.

That sort of effort will turn a lot of people off before they get to the end. Courses like this one or this one on web development will teach coding and get you building cool things much quicker, which will help build your confidence.

No, not at all. As mentioned previously the course is aimed at a range of experience levels. The only high expectation is the amount of hours they expect students to put in outside of the lectures. The course is broken up into the weeks it would be taught at in Harvard.

When doing it online though you can take as long as you want to complete each week. You can expect to spend 10 to 20 hours completing each lecture and pset.

On top of that, the lectures are around 2 hours per week plus a final project to complete at the end. I really loved the early weeks of the course, weeks 1 to 4, when you work in C. Going through things like what pointers, linked lists and other data structures really are was fascinating and exactly the type of thing I wanted to learn about in this course.

That said, I still enjoyed them. If you want to compare your code against what I submitted to see my approach, here is a link to the Github.

Overall the course took me hours, over 19 weeks, to complete. Of that time, I spent 73 hours over 7 weeks following the lectures and doing the psets, and then 60 hours over 12 weeks on the final project.

Note: Week 9 had no lecture or pset and week 10 took so much longer as it had the final project. So I came up with the idea to build off pset8, which involved getting stock market prices and using a Flask server, and make a game of it that I could run in a container and deploy on AWS.Introduction to the intellectual enterprises of computer science and the art of programming.

This course teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, and software engineering. Problem sets inspired by the arts, humanities, social sciences, and sciences. Course culminates in a final project. Designed for concentrators and non-concentrators alike, with or without prior programming experience.

CS50 Logistics

Two thirds of CS50 students have never taken CS before. Among the overarching goals of this course are to inspire students to explore unfamiliar waters, without fear of failure, create an intensive, shared experience, accessible to all students, and build community among students.

No books are required or recommended for this course. However, you might find the below books of interest. Warren Jr. Problem sets are programming assignments. CS50x does not have deadlines for problem sets. You are welcome to work on and submit them at your own pace.

The climax of this course is its final project. The final project is your opportunity to take your newfound savvy with programming out for a spin and develop your very own piece of software. You may implement your project in any language s. All that we ask is that you build something of interest to you, that you solve an actual problem, that you impact your community, or that you change the world.

Strive to create something that outlives this course. Inasmuch as software development is rarely a one-person effort, you are allowed an opportunity to collaborate with one or two classmates for this final project. CS50x does not have a deadline for the final project. You are welcome to work on and submit it at your own pace. However, there remains a line between enlisting the help of another and submitting the work of another.

This policy characterizes both sides of that line. The essence of all work that you submit to this course must be your own. Collaboration on problem sets is not permitted except to the extent that you may ask classmates and others for help so long as that help does not reduce to another doing your work for you. Below are rules of thumb that inexhaustively characterize acts that the course considers reasonable and not reasonable. If in doubt as to whether some act is reasonable, do not commit it.

If the course determines that you have commited an act that is not reasonable, you may be deemed ineligible for a certificate. Syllabus Introduction to the intellectual enterprises of computer science and the art of programming.

It only takes a minute to sign up. My assignments were correctly executed as per almost all conditions of the automatic evaluation but in the CS50 Gradebook, my grades are 1, 0, 0.

The grades are out of 1, so 0. In order to earn the certificate, you must get at least 0. You can run check50 to check your programs before submitting and see your results. For example, in pset1, you have the mario check:. Psets 0, 4, 7, 8 and the final project have no automated checking and are therefore simply graded 1 if you submit it and 0 if you don't.

You can resubmit your psets as many times as you want until the deadline and they will be regraded. Be sure if you resubmit, that you resubmit the entire pset and not just part of it ie, if you resubmit pset1, be sure to include hello.
