get a masters degree

I know that I need to take my GRE or GMAT. I have to have three recommendation letters. And last but not least I have to write an essay that’s 500 words. This depends on the school I choose though and my GPA isn’t a 3.0 + so… it’s going to be much harder for me to get into Grad school. I have thought about what it is I would like to study and can’t decide between a Masters in Library Sciences, Masters in Music Technology, or a Masters in Business Administration. If I choose the MLS degree from Indiana University I would like to focus on Creating Technological (Software) Libraries to make them more readily available for use in Medicinal or Electromagnetic Research. If I chose Music Technology at IUPUI then I would like to work on a project with musicians. I know that’s vague, but my idea is good. If I work towards a MBA then I would like to apply my knowledge to assist my employer or use my own company as a project.
