Joining the seminary of Lazarist priests, the only high school in Diamantina At the age of 12, Juscelino joined the seminary of Diamantina in order to get his secondary school education. His mother had made a special request to the Lazarist priests. This was the only possible place in the city to get his secondary education. As soon as he entered the seminary, Juscelino made clear to the priests that he felt no vocation to religious life. After three years, even before his 15th birthday, he concluded his studies at the seminary.
The idea to become a physician had always been strong and present, and made him continue searching for new ways to further his knowledge. He still lacked some courses to conclude his high school education, and they were only offered in other cities. He soon found out that it was possible to take these courses through a system called “exame por decreto” at the time (governmentally certified exams). Under this system, candidates studied by themselves, took exams, and could work towards a high school diploma. Juscelino devoted himself to his studies even more than before. There were twelve exams to take. After completing them, the next step in reach would be university.
