Career in Photography...?

Here's the sitch: I just got denied from my safety college in NY. Apparently being Senior Treasurer, a Yearbook photographer, leader of my school's video production class, and having a 3.4 GPA doesn't count for anything.

My ultimate goal is to become a photographer there for a fashion magazine. So my questions are:

1) How should I go about trying to get a job in the field?

2) Is college necessary for it? Do most people have a degree in it?

I would also appreciate it if I could get some critiques for my photography.
