Vestibulares are entrance exams used in several countries, particularly in Brazil, to assess students' readiness for higher education. These exams typically cover subjects such as mathematics, Portuguese, science, and humanities, and are a crucial step for students seeking admission to universities. The format of vestibulares can vary, with some institutions using a single exam while others may have multiple stages. Preparation often involves extensive study and practice, as the competition for spots in popular courses can be intense. Success in these exams is essential for students aiming to pursue their desired academic paths.
