I just looked back on the PDF of the CommonApp I sent to several t20 colleges. I realized I had made a massive typo, my mom, first name Patricia, I listed as a father. Should I call all my colleges, or is this clearly a typo? Will I be rejected immediately for said typo?
Unless you applied to really conservative religious colleges, no.
Some colleges will allow you to update personal information on their applicant portal, so definitely check that and see what you can do.
Do you really think this could get you rejected?
