Extended Essays in Computer Science are not easy to do. Computer Science is counted as an experimental science by the IB and thus requires you to do some kind of experiment in the realm of computer science and then report your findings.

As so few students attempt a CS EE every year, coming up with a ‘good’ CS EE topic will be half your struggle.
