Welcome to




CS EE World was created in 2019 by a May 2019 IB graduate upon the realization that there weren't enough free Computer Science Extended Essay (CS EE) exemplars online to properly guide IB students. As the notable website IB CompSci Hub says, "Extended Essays in Computer Science are not easy to do," so students need the guidance to write good papers.

This site hosts the ✨world's largest✨ collection of free original CS EEs, each of which was donated directly to us by previous students. We also include some links to EEs existing elsewhere online. Feel free to download from our collection, and please remember to donate your EE to us when it's completed and you've gotten your official IB grades! 


Our Collection

Our Collecton

At the time of writing this, the latest official IB EE guide came into action in 2018; pre-2018 EEs should be considered old. Nonetheless, we'll happily accept pre-2018 EEs, and readers are still encouraged to consider reading pre-2018 EEs - there are still things to learn from them.

Number of EEs available: 45


If you or anyone you know has written a Computer Science Extended essay, please help CS EE World and International Baccalaureate students around the world by submitting it to us! We would appreciate it very much. Remember, the EE doesn't have to be perfect for people to learn from it!

We have a consent form available for teachers if they want a way to get consent before submitting EEs on behalf of their students. This is completely optional; it's just for your convenience.

Please don't contact us for help with any part of the EE ideation or writing process. That's not something we will actively help you with - go to the IB Discord and IB Subreddit instead. All the best!

Thanks for reaching out! We'll get back to you when we can.
