The new Common App is so confusing. There doesn’t appear anymore to be a section that allows me to request an official high school transcript to my HS counselor through the Common App. Instead, each school has a different process, with some asking me to upload a high school transcript myself? (like Duke). That’s not an official transcript at all.
Each high school has a different process for requesting a transcript. You don’t send it, they do as part of a packet. In my school, you fill out a “blue card” for each college. In my kids’ school, it’s a form in triplicate.
