i'm in some communication theory class and the instructor said "this is the core class for the communication minor so if you're already in here you might want to look up the rest of the requirements" but when I tried to do that, I found nothing. Apparently the only two minor requirements on the website at ALL are IST and physics

lol dont use the UMR search if you can help it, use goggle.

I hope this is what you were looking for.
You SHOULD have been able to look this up in your (larger) course book thing. but comunications 'maybe' is new or something.

If that's Dr. Malone your talking about, then he's probably talking about the TECHNICAL communication minor. Which is new and does include some IST classes. I think Web Design is one of them.

It's UMR. Prereqs don't mean anything.
