1st generation college students: What's your story?

I’m a high school junior, but will (hopefully) soon become a 1st generation college student. I can definitely say that my education might have been a bit different than some others, but I wanted to know if it was that way for everyone who was 1st gen.

As a first generation college student, what has your education as a whole been like both in high school and in college? Did you have any difficulties when it came to school? Did you ever feel at a disadvantage in any way?
