I am super excited to say that my husband graduates in 1 month!!! We got through this with a lot of pre planning. He had 2 years of prerequisites to complete which gave us time to save as much as possible. He took 1 prerequisite a term while working full time. When he began school I got a job working 32 hours a week at a low wage as our only income. We took the 2 years to tweak our lifestyle so that it was not so drastic when our income was so small. Due to child care assitance not covering care for study time I worked the 32 hours because we rely on family to help 2 days a week and there is no money to pay for child care. I earned so little that I was able to defer my student loan for 1 year.
Comcast had a new program for low income families which provides low cost internet service. I am unsure of the name of the program right now, but you could try to google it.
My husband takes lunches to school. One thing that has helped is the local bread outlet. We get decent bread for 1$ a loaf or less and make the trip once and buy enough to stock the freezer. The thermos and to go coffee cup are helpful. We got some instant coffee for the long days away. He will take his cup and just get hot water at a coffee shop or school kitchen.
I also diligently scoured the web for the best textbook prices and my husband is keeping the books in good condition to be able to sell all of them as a package deal to an incoming student.
Don't forget to ask about student discounts for various things. A lot of times students can get free bus passes.
Good luck everyone. It is totally scary yet totally possible.
