I am starting dental school this fall 2010 and my parents could not help me financially. it was also out of a question to take too many loans... so the question is: how can you attend dental school and work without affecting your grades. if this seems impossible for you, listen to how I managed till now.
I work one night a week ~ 3 hours as a lab instructor in a local college near my house. I have a T.A who does all the quizes and correct them -> $8000/year
then there are jobs that let you study while you study at night such as lifeguard or security gard or doorman in a nice building two nights a weekor over the weekend. those job require almost no activity from your part so you can pull out your laptop and study + you get paid while doing it ;-) ~ 10 hours a week @ 12$ an hour this is almost 500 dollars a month or 6000 dollars a year without affecting your studies....
then, keep in mind that while you need to put a lot of time to sit and study... you also have to work out in order to avoid becoming a zombie... so you can also coach someone for like 10 bucks an hour twice a week; this let you workout, help someone and make 80 bucks a month. (every penny is important!!!!)
another way stated earlier would be to apply to as many scholarshipe as possible.
then for those who have some sense of a business mind you can start to buy/ sell stuff online. it takes very little time and you can make a lot of money!!!
hope this help
