A lot of people will tell you that comms is easy. And, for the very basic gen ed classes like public speaking, it's not too bad. Comms is a very wide field of study though and some of the specialty areas can get pretty intense.
My wife's comms undergrad degree included watching Hitler's speeches (in German, after taking four semesters of German) and then contemplating how he was able to move an entire nation to ruin and destruction - that's not my idea of "easy". Her thesis examined the difficulties inherent in cross-communication between socio-economic population divisions.
My comms specialty area is writing pedagogy - not nearly as "hard" as analyzing propaganda in another language but also far from "easy".
When a comms major is assigned "a paper" - it's usually not a few pages long. This is a major that produces some serious writing. Assignments of 20+ pages in a week are not uncommon. That's also not "easy". If the paper is only a few pages - it's usually due today, not next month.
I personally think math is "easy" - there's usually only one right answer (objective) and nobody's opinion about it (subjective) really matters. ☺ 2x+4=6 means x=1, always. "True Blood is really a social commentary on race relations in the southern US..." is subject to much debate and discussion.
I've found that there are two skills that define highly successful comms students. First is an outgoing/extroverted personality. People that can't talk to people (or in public) don't do too well communicating. The other is a very open mind. Comms students explore a lot of controversial ideas from a variety of perspectives. An effective communicator must be able to at least understand differing perspectives even if he doesn't agree with them. You'll have to be open minded enough to see through the message on top to the wider implications of what you see, hear, write, or read.
You'll be given the opportunity to learn to write well, speak in public, design presentations, and analyze messages. If you learn those well, there are great opportunities for you. If you don't, the degree won't help you a bit. Poor communicators don't last in the field very long at all.
"The ability to communicate well orally and in writing" is a very common job specification in every field. The other common specification that can't usually be met by HR is one for higher math skills. It would appear that every other skill employers need they can find people with - these two are apparently hard to come by. Any person that develops both will have huge opportunities.
I would suggest, unless you'd one day like a job where you "talk about talking" (some people have that job) or "write about writing" (people have that job too), that you either double major or minor in something else of interest. Communicators generally communicate about something. You need to learn the 'something' part too. Many comms grads lament that they can't find a job in the field. That's often because they have no complimentary skills and no direction toward a specific industry. Half of your classmates will decide to minor in Literature or English - that's probably not a good idea except for those planning to teach in the public schools.
Tech writers need to know about whatever it is they're describing (computers, engineering, science), journalists need to understand the news they write (business, politics, arts, sports...), media analysts must understand the nature of the genre they're analyzing (theater, news, arts, etc...), Stategic comms need to understand business and finance, PR needs to understand the industry they're publicizing, teachers need education theory and pedagogy skills, etc....
Many people look at it as an impractical major. They obviously haven't looked around in a while - our society is bombarded with information. Communicators are the gatekeepers of that content. Everything you see on TV, read on the web, hear on the radio, see in an ad; every product package that you pick up (or not), etc... is communication. Commercial providers of that content pay good money for people that can generate quality. Been to a bookstore lately? One guy didn't write all of those books. The folks that wrote them didn't do the edits. The copy editors didn't write the marketing.
There's another hidden advantage to being a comms major in college. When a comms major writes a history, science, music apprec., etc... paper, he usually gets an A.
