HUGE Discrepancy Between Harvard and Princeton Financial Aid Class of 2022, RD

Here’s the gist of my story: I was checking my financial aid info last night and I realized that the difference between Princeton’s and Harvard’s offers was over $20k (which makes a huge difference for my family). Princeton’s was higher. This leads to me a few questions:

  1. Did I do something wrong on Harvard’s application? I went into my portal and checked to make sure my financial application was noted as complete (which it was).

  2. Does anybody know why this is happening? I thought Harvard was supposed to have the best financial aid packages.

  3. Has anybody else had a similar case?

  4. Should I appeal Harvard’s offer and if so, any guidance and/or tips?

Thank you so, so much for all of your help.

I realize I put this under the wrong college. Please ignore this.
