Masters Discussion Forum

I have a Bachelors of Science but would like to pursue a masters in political science or public policy. Can anyone give me any recommendations in what to do or where to go since many schools require some more schooling and research that may have been outside my overall learning experience. Almost all the schools require a similar bachelors degree but that definitely feels excessive since I have bachelors degree already. Feeling lost on exactly how to go about this so any helpful advice would be appreciated.
Thank you.
