Choice of grad school? Have a hard time choosing?

Well, with the economy being the way it is and jobs being hard to get, I would recommend doing an internship. It's the easiest way to get your foot in the door with a company. The reason for this being is because a company can have someone do a job for cheap or even free as opposed to having to pay someone a salary. Then after you have worked there for a few months or maybe a semester, they will usually hire you for a full time position (if you did well). It's easier to get a job after an internship because your employer already knows what you can do, and you're already trained and used to working with a company as opposed to someone else who's looking for a job. Don't go to grad school unless you really want to, and most of them these days prefer people who have had experience in the working world. Also you need to get a masters before you get a PhD. But yea get a job in the working world so that you can find out what you like and don't like so that then if you decide to go back to school, you'll know what you'd like your concentration to be.
