^^^ LOL... don't listen to brave in this case... you won't see too many communication majors at top law schools...
HERE IS YOUR PLAN:
1) spend all of freshman year taking a variety of intro courses that seem different, interesting, strange, unfamiliar, and/or challenging. Use these to also fulfill whatever silly requirements your institution of higher learning necessitates. This will allow you to explore a variety of subjects that you may not even know anything about and knock off some pre-reqs / crazy college reqs..
2) spend sophomore year taking some higher-level classes in those subjects that most peaked your interest freshman year... declare your major by the end of the year
3) junior... fulfill your concentration requirements and start to think about law school
4) senior... don't screw up your grades while knocking off final requirements
If you are thinking about impressing adcomms, avoid business degrees or other "vocational" degrees... strong liberal arts concentrations are always good for law school (i.e., history, polisci, philosophy, etc)... while these may not set you apart from the millions of other law school students applying to law school, they are still excellent preparatory backgrounds for law school... do well in them and adcomms will take notice... hard sciences are also good because law-types are impressed with hard sciences, probably because most law types shy away from them...
I would say, if you are sure you want to go to law school... take a hard liberal arts or science path... I would choose the specific path after exploration and on the basis of 1) interest and 2) chance of success... hopefully these two factors will coincide... ultimately, adcomms will be impressed by success in a rigorous program... get a 4.0 in engineering, history, physics, or philosophy at a solid undergrad and you will get a solid check in the box for this portion of your LS app
