Risk

Im not going to say chance, thats cliche. Going on topic, I dont have any rec letter to present to the table, however I did excel at my HS with A’s and whatnot. My ACT isnt 36-perfectist score, minus 12 you get close. I am currently applying to 2 colleges with acceptance over 50% and 1 Ivy. I am very poor. First kid to go to college in my family. I am mostly concern about rec letter. What are the risks of not getting accepted?
