By Suraj Chaudhary

Are you looking for a way to study Computer Science at Harvard University for free? Do you want to get a free certificate issued by Harvard University?

If so, you’re in the right place.

In this article, I’ll show you exactly how you can take the most popular course of Harvard University for free and also get a certificate.

Have you ever wanted to learn programming or build your own apps, websites, games and so on? If you have, CS50 is the way to start. CS50 is an on-campus and online introductory course on Computer Science taught at Harvard and Yale University.

Undergraduates and high school students take this course from all over the world in order to learn the basics of Computer Science and Programming.

The best part is: CS50 is totally FREE to take

After taking this course, you’ll have a good knowledge of programming and programming languages such as C, Python, SQL, HTML, and JavaScript.

Secondly, you’ll have a good understanding of Computer Science concepts such as data types, algorithms, arrays, and data structures which are the base of programming.

It is available for free on EdX with a range of certificates available for a fee. In this blog, I’m going to tell you everything you need to know about this course, in addition, to how to get a certificate from Harvard for FREE.

Why to take CS50?

In this era of ChatGPT and DALL.E, many people are losing their jobs. The reason? AI.

We have always seen in movies how robots and AI destroy the mankind. While the current situation is not that extreme, we have definitely come a long way in terms of computer advancement. It is not just advancement but also the amount of money you can make as someone who knows programming is higher than ever.

You cannot become a programming wizard in a day. It will take you a good amount of time. And if you don’t have the right guidance it will take you even longer, maybe over a year.

That is where CS50 comes in. YouTube has a lot of videos that you teach you incredible things, but the lack of a proper structure from beginning to advanced level is a pain.

If you start learning programming from YouTube, it will take you ages to learn programming because you have no idea where to start and which videos to watch. Why? Because you don’t know what you don’t know.

CS50 has a properly structured series of videos that doesn’t expect you to know anything prior to starting this course. Fun fact: More than 50% of the students who take CS50 have never taken a Computer Science class before in their lives, yet all of them complete this course with a good grasp of programming.

Things You MUST KNOW Before You Start CS50

#1: You may find solutions to the problem sets on the internet, however, you can’t just copy-paste. Harvard has a very effective algorithm that detects if your solution has been copied from any previous solutions that were already submitted. If yes, you’ll be removed from the program, and if you’ve already got your certificate, it can be revoked. For more details, read Harvard’s Academic Honesty Policy.

#2: If you want to receive the free certificate, you must go to but NOT because they are different websites (one has a black-white interface, and the other has a red-white interface).


To sum up, CS50 is an extremely valuable course that can transform the way you think about computers.

If you are a high school student or recently started college, and are interested in programming or Computer Science in general, you should definitely take CS50.

Subsequently, it also has additional in-depth courses called ‘CS50’s Web Programming with Python and JavaScript‘, ‘CS50’s Introduction to Game Development and ‘CS50’s Introduction to Artificial Intelligence with Python‘ which you can take after CS50’s Introduction to Computer Science.
