Welcome to




CS EE World was created in 2019 upon the realization that there wasn't a sufficient number of free Computer Science Extended Essay (CS EE) exemplars online to properly guide IB students. As the famous website IB CompSci Hub states, "Extended Essays in Computer Science are not easy to do," so students need the guidance to write good papers.

This site has a collection of both original EEs (meaning they were donated directly to us) and EEs from the web. We've included EEs from the web for convenience, to make them easier to find. Feel free to download from our collection, and please donate your EE to us when you're done! Please make sure you donate your EE only after you've gotten your official IB results.


Our Collection


Note that at the time of writing this, the latest official IB EE guide came into action in 2018, hence pre-2018 EEs should be considered old. Donators should note, though, that we'll happily accept pre-2018 EEs. Readers are also encourages to give pre-2018 EEs a try as they may still learn from them.

Number of EEs available: 26


If you or anyone you know has done 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 the EEs of their students. This is completely optional; it's just for your convenience.

Please don't contact us for help with any part fo 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.
