Is this referencing two separate majors, or is there one major called “Comp. and Electrical Engineering”?
They are two majors housed in the same department.
Sorry for being crabby, but the answer is a sublink on the link you posted. It gets my hackles up because so many students ask questions here that are super easy to find just by using Google. I wonder how they’ll succeed in more complicated things like scheduling classes or paying taxes. #facepalm
The nice thing about taxes is that if you turn to Google, one of the first things that comes up is TurboTax, which makes an incredibly opaque system slightly less opaque.
Ahhh…The Google. 
Now that we’re on that subject, I helped my son do his first taxes via TurboTax. It was INCREDIBLY easy and free for low wage earners.
Sadly I no longer get it free, but the time I save is more than worth the money.
Even so…not as easy as clicking the “About Us” link. :-/
There’s a web version of TurboTax that you can use if you make less than XXX, free online filing Fed and State. Good stuff 
That’s the one my son used. It even helped him calculate Elbonia taxes (well not quite, but both OR and CA).
