You decided to enroll yourself in a university at the high-kingdom university where you saw dozens of people leave the school if they had armor, and clean clothes for adventurers with degrees rolled up as they had them in their hands. You of course saw that they were graduates, so it was your turn to get one.
As soon as you entered the building, you spotted that most of the students that went to the HKU, didn't have any degrees rolled up in their hands, aside from the one's you saw just leave seconds before you arrived, so you would have plenty of classmates. Just then, you arrived at the elf woman who was sitting at the front desk. "Welcome to the High-Kingdom University," she says. "How may we help you?" You explain that you were here to get enrolled in the University, and she asks for your diploma.
You were homeschooled with Sister Gronum all your life, but luckily she'll was able to give you a diploma to explain which career you were going to take while at the same time studying at the University.
