When did Pele's brother graduate from the University of São Paulo?

I couldn’t verify a graduate date for Pelé’s brother from the information available here. The strongest reliable match identifies his brother as Jair Arantes do Nascimento, known as Zoca, but it does not provide a University of São Paulo graduation year.

What is known

• Pelé’s brother was Jair Arantes do Nascimento, nicknamed Zoca.

• The sources gathered here do not confirm that he graduated from the University of São Paulo, or when that would have happened.

Practical answer

If you need the exact graduation date, it would require a more specific biographical source or an academic record mentioning Zoca’s enrollment and completion date.

TL;DR: I can confirm the brother’s identity, but not a verified University of São Paulo graduation date from the available sources.
