If I were you, I would either pull back my acceptance or do the military route. I obviously don't know your financial standing, but if you have to take out the maximum needed, then you're looking at close to $450,000-$500,000. That's before your wonderful interest rate of 6.21 or 7 21% is even considered.
Have you sat down and calculated what your payments would need to be after you graduate to get out of debt? I was accepted to NYU when I applied, and just for sh*tz and giggles, I wanted to see how much my loan payment would be after I graduated. Well, without boring you too much, if I took out the maximum amount needed to cover everything I needed to get through school at NYU, and pay off the debt in 10 years, then I would have had to pay, get this, $6,3000/MONTH. That's over $75,000/year JUST in student loans. Let's say that after you graduate you do really good and start making $120,000/year right when you get out. Well shoot there is income tax, that will knock you down to roughly about 85-95k/year depending on what state you live in. Oops, can't forget about those student loans! Now you're left with 10k/year. You see the problem? For you to live a very frugal life off of 50k/year after loans, then you would have to make over $200,000/year right out of school. Again, do you see the problem? You simply can't pay back your loans after you graduate if you decided on a 10 year fixed payment plan.
You would have to pay back your loans for over 30 YEARS in order for your monthly payments to be relatively reasonable of about $2,700/month. Obviously, going this route and extending your pay period only adds to the total amount of interest accrued. For me, if I were to go to NYU, take the full amount needed to go to school there, and pay it back over 30 years, then it would have costed me, counting interest, by the time it was all said and done, just over $1,000,000. And that's just your student loans! I'm sure that someday, you might want a house, your own private practice, and a few kids that will suck you dry of money.
Needless to say, if you go to NYU and don't do the military route, then you WILL be a slave to Uncle Sam for decades.
