The app's content

• Questions and essay topics come from INEP's official exams and are reproduced as they are.
• The classification of questions by topic and comments generated by artificial intelligence may contain mistakes. The answer key is always the official one.
• Mock exams do not predict your ENEM score.
• Recommendations, goals and schedules are study suggestions, not a guarantee of admission.
