I'm in my second year of graduate school. I recieved my BA in 2002, went to Italy for the summer to get away and then went straight back to graduate school in the fall. I am personally really glad that I didn't wait. Where I was living and where I graduated from college didn't have any opportunities. So, I moved and started graduate school and now work part-time in my feild while I am attending classes. It gives me a chance to make connections, and when I do graduate, I will be able to land a position anywhere in the city. It really opens so many doors for you, not to mention a salary increase.
I have also had many friends who went to graduate school after working a few years. The hours and the pay both got very old very quick and they didn't see themselves advancing without a higher degree. All in all, it just depends on what you are looking for and what your major is. Let me know if I can help! I have some great GRE websites and graduate school websites as well! I would be happy to answer your questions, because I wish someone was there to answer mine, I kinda went into it blindfolded! Good luck!
Let me know if you need ANYTHING!
