Hi,
I graduated from a non-accredited University in Biomedical Sceinces 2 years ago.I rememeber feeling devestated by my grade however I pushed myself to apply for as many jobs as possible that summer. It paid off, because I became employed by September (3 months after).
My employer is an IVRs company i.e. a sort of service provider for clinical trials. My role is "project coordinator".
I know what it's like once you've graduated, you don't know about the various jobs which are out there (I certainly didnt know about my job/business whilst I was studying). My advice is to speak to other people in a similar position to you with jobs. See if your friends could refer you, provide your CV to a recuitment agency, ask your parents for help?
Unfortunately due to today's economic climate, us graduates have to start out doing whatever. Then as you gain more experience, you'll find out more about what you like and you'll be more appealing to prospective employers with even an temporary admin/office job.
Rememeber, your degree is valuable and rock solid so yes a 2.2 is still impressive. Don't feel disheartened, you've done the hard bit (completing your degree) you've just got to boss it now ;-)
