Elementary Education
In the US, community colleges will accept everyone with the caveat that you take placement tests and may have to take remedial classes first for no credit.
Once you have an associates degree from a community college, it is fairly easy to transfer to a larger university.
Fill out the federal student aid form, the FAFSA, and they will determine whether you are eligible for grants, which do not need to be paid back, or loans. It's based on your family income.
I was eligible for loans to cover tuition and a little bit extra. However, I did not have to pay room and board as a commuter student. Living on campus might have presented a financial gap.
They seemed to give out these loans freely. My husband made a decent income at the time, so it seems likely that most people could get their tuition covered with loans.
And, I now owe the federal government a giant pile of cash!
