I can only give advice if your J school also emphasizes on Mass Communications (Advertising, Marketing, PR), as that is what my school did. Best thing to do is concentrate on the major you want SOLELY, take hands-on classes, and get cracking on them internships. Also, get to know people in the industry you want to work. Study up on the top spots in your area (or the area you would like to be), introduce yourself, show you are personable and eager to learn, as you must first learn to market yourself before you can help anyone else out.
This.
im in journalism school right now. Im a Ad/PR major but had to take journalism classes too (duh). but like karl said, best thing to do is focus on your path and take hands on classes. also talk to your teachers about internships and hookups.
edit: I wasnt even aware u needed a folio ta get in to j school....then again it might depend on your degree plan.
