I read on the Caltech website that they accept self reported scores from the Common App but on the College Board website it says that scores were due on Dec 31. Is Dec 31 the deadline for people who were accepted through EA?
Cal-Tech’s application deadline this year was Jan 3 and you could self-report scores on the app. Not sure what CB is referring to although possibly it is a prior year app deadline that CB failed to change for this year. You should not assume CB is always providing current information about a college’s requirements. For example, it has a list of colleges on its site that supposedly require “all scores” which list has now been wrong for at least 9 years, see https://secure-media.collegeboard.org/digitalServices/pdf/professionals/sat-score-use-practices-participating-institutions.pdf
