What are my chances of getting into a top M.A. in International Relations program?

<p>I graduated in 2010 from the University of Michigan in Ann Arbor as a political science major with a GPA of 3.2 and I am currently working as a parelegal at a DC Immigration Law Firm. I have some experience working abroad from my summers as a undergraduate student at Michigan but it isn't much. If I were to do well on the GRE or GMAT, do you think I could I have a chance at applying and getting into a school like SAIS or Fletcher by the fall of 2012?</p>
