I got low SAT scores

I got 700 in my SAT, does that affect my changes of getting into a 4-year college? Can I still reicieve financial aid?

Yes - a 700 is very low. You’d be better off applying to test-optional schools, or better yet, gaining the reading/writing/math skills and testing strategies needed for the test.

Another option might be to start at a community college and transfer after a year or two.
