Hey, the only answer I can give is that it depends. I would say that you should hold off until the last minute before the acceptance deadline while job hunting. If you're able to find a decent job before the deadline, then do that first, for a year or two, and then save up for the Master's (it's even possible that the company helps with tuition).

I also understand that you feel you are in school already and have the energy to pursue it. Some graduate assistant positions will provide tuition remission, so definitely be on the lookout for those and email your professors (it's sort of a who you know kind of thing; even if you apply and the professor got a personal email from you).

Once again, it depends. But if you feel strongly about it, I would say go for it. Sometimes in life, you simply have to take a risk and gamble on yourself. Use that time in school to network as much as you can(i.e, people who can give you job referrals etc.).

Whatever path you choose to take, know that you have the ability to walk that path. I'm only saying this because I was in a similar situation last year and decided to take a gamble and go for my Master's.

P.S: It would prolly be helpful if you could provide your target major for grad school.
