Should I even apply, and if so, to what schools?(I have no idea what I'm doing please help)

I wouldn’t say my grades are that great: my school is mediocre, has like ~300 students and I’m not even in top 10 grade-wise. I didn’t apply early decision because I was afraid that I’d get cornered into taking bad aid (like a lot of loans). As for the aid itself, my need is basically full need. It’s kind of complicated, because I’m raised by a single mother and we are on the poorer side, while my dad is actually pretty wealthy for polish standards, yet I don’t think he could scrape up more than like 30 thousand USD and it would still be a huge burden on him (like most of his savings; he has more children, so it’d be pretty bad if he spent all his money on me), I don’t really want to consider it. Although I might not qualify for 100% aid, I need all the aid I can possibly get.

Thank you all for your help <3 In case anyone else stumbles upon this post, If you know about any other schools, not brought up above, that are generous to internationals, please let me know!

Oh, and what do you guys think about that middle-school exam, it’s probably my biggest achievement ever (i did like 2 mistakes total on all of the subjects - math, polish, english basic, english extended, history and science), still it was kind of a long time ago.
