Cultural Tip
In Brazil most schools and universities handle enrollment online through a portal. Deadlines are strict, and missing them can mean you’ll have to wait for the next semester. When asking about enrollment, it’s polite to add a thank‑you after the answer (e.g., 'Obrigado!'). In some regions, 'matricular' is more common than 'inscrever', especially in higher education.
