We will never know the answer to this, but it wouldn’t surprise me if listing all 8 Ivies on your FAFSA didn’t at least slightly hurt your chances. If I saw that, and was evaluating your application, it would immediately set off my “Does this person really care about my school, or are they solely interested in prestige” and I might view the rest of the application with heightened scrutiny.
No evidence for this beyond the fertile confines of my own mind, but it’s something to think about.
