Need help making a plan- What to do if my parents cannot afford the EFC?

This may not be what you want to hear, but your list is really reach heavy, with only W&L as a potential match, and UW-Madison as a safety but because they don’t offer much aid, you won’t be able to afford going there so its not really a safety. Focus on the list from ucbalumnus - if all the deadlines have passed, do not go to CC. Instead, take a gap year, focus on polishing your profile (take more SAT2 tests for example), apply early to schools that full need and/or offer full ride, and your chances of getting into a good school at the amount you can afford will be much higher.
