To address some of the issues surrounding aid for disadvantaged students:
1) if you believe you qualify, you need to fill out the nycom form and also submit copies of your parents tax return from 2009. it's worth it because you can receive a few hundred to thousands in GRANTS per semester to help with your tuition. even if you don't get it your first year, you should request consideration for that funding in subsequent years (if your family's AGI meets the criteria for economically disadvantaged).
2) everyone should be maxing out their federal sub (6.8% interest rate cap) and unsub loans (6.8% interest rate cap). i think these loans will not be covering your entire tuition cost, so you should take out additional loans in the form of gradplus (8.5% interest rate cap). As tempting as some of these private loans may be, I would do a lot of thorough research on it before I commit to any of them - interest rates are usually capped at a higher rate or not at all.
3) as to living expenses - it depends on whether you will be renting an apartment, house, or commuting from home. For those that are going to be "independent" as in living in an apartment/house, consider utility fees, ie electricity, gas, and cable. In addition to that, factor in that you will need to eat and that you will definitely be purchasing review books, etc. if you're living at home, you probably only need ~3-5K.
4) to save yourself some money and time - buy a few pairs (2 minimum is best) of generic blue or green scrubs for anatomy lab and OMM lab, a pair of scrubs at school will cost you ~30-40. purchase a stethoscope and do not buy it from school when the rep comes. you may want to purchase an otoscope/ophthalmoscope as well.
on that note... we also have newly marked down, cheapest available prices on textbooks/review books, atlas, flashcards... feel free to take a look. =)
