as far as the max loan needed - I went to school at a private school - graduated in 2005 - tuition at the time was 20k (I should have went to public school - but you know - we all pay stupid tax).
I worked 30+ hours a week during school - 60 during the summer - work hard, live like a pauper - once month of rotations at the VA I spent a grand total of $30 on groceries for a month - it is possible, you will thank your self when half your income doesn't go to paying off loans. I got lucky - my loans are fixed at 1.9% - new grads will not be that lucky.
Borrow as little as possible - you can have fun cheap - study hard, work hard, find those jobs where you can work a couple of hours here and there - my hospital was 2 miles from campus and I had a job where I could basically make my own hours doing narcotic controls - did so when I wanted to as long as the job was done. Get a job bar tending - you can make good money - plus have late hours to squeeze more work time in.
