I’m confused about UPenn’s self-reporting policy – do you have to send Subject tests officially or is self-reporting them fine? https://admissions.upenn.edu/admissions-and-financial-aid/preparing-for-admission/First-Year-admission-checklist-deadlines and https://admissions.upenn.edu/admissions-and-financial-aid/what-penn-looks-for/testing say different things ("Penn will review self-reported SAT and ACT test scores from first year applications attending high schools in the United States. SAT Subject Tests, TOEFL, and IELTS scores must be sent through official testing agencies to be considered with your application. ")
