I agree...it's not worth applying to b-school straight out of college for several reasons...it's a lot harder to get into a decent school, you won't have as much to contribute to case studies and course discussions because you have no experience to base your viewpoints on, you will be behind your more experienced classmates, recruiters are looking for people with 3-5 years of pre-MBA work experience, you won't get as high a post-MBA salary as those with more experience, and you won't have had an opportunity to finetune your career goals prior to pursuing an expensive MBA.
I wanted to go fresh out of college too, but am SO glad I didn't. My career aspirations totally changed after a few years in the work force, and working for corporate America and small business and start-ups during the first 5 years of my career really helped me narrow down what I wanted to do -- and in what environment. I originally wanted to be a big ol' VP of marketing for an consumer products company, but have moved into a more entrepreneurial, small business mode. Very, very different.
Forget the GMAT for now, and focus on finding a career-building job and community activities that enable you to develop leadership skills. In 2-3 years, go for it with a GMAT retake and a solid vision of where you want to be in your career and how an MBA will help you get there. Right now, you just won't be competitive and it won't be worth it.
Good luck!
