well it’s specifically a pretty good pathway if you want to work on technology because you’ll be proficient in both hardware and software, probably the best double for that, otherwise you can work as an electrical engineering obviously which involves stuff like energy, mining, industrial automation, electronics, embedded systems etc
specifically you’d be learning how to design electrical circuits and analyse them, program microcontrollers in low level programming languages, advanced data structures and algorithms, electromagnetic physics, electrical machines, analog circuitry, and how to use signals in systems for the electrical engineering part of the degree
then for computer science you’d be going into things like operating systems, networking, much deeper algorithm stuff, machine learning, databases, more higher level programming languages than electrical engineering, etc. essentially electrical engineering is more focused on hardware whereas compsci is more focused on software
alongside those classes you’d be learning a fair amount of maths especially for electrical engineering which needs some pretty sophisticated stuff, compsci also has some math but much less than electrical engineering, more so in the logic realm than anything else. electrical engineering also obviously has a good amount of physics to learn because you need to understand electromagnetism and potentially optics
