Wow, OP you started off with a question about AP Lit and lucked out by getting some apparently very needed advice.
As noted, start with informing yourself about 1) financial aid, merit aid and YOUR family’s income, asking your parents their expectations about how much they can pay and 2) how to put together a list of safeties, matches and reaches and 3) start with the safeties – they are much much harder to come up with!
