About this app

Mathesis Concursos is an independent study app. It does not represent the Brazilian government, the Federal Police, the Federal Highway Police, INSS, Transpetro, DATAPREV, Banco do Brasil, Caixa Econômica Federal, Fundação Getulio Vargas (FGV), Cesgranrio, or Cebraspe.

Prepare with REAL questions from official exams — and understand the reasoning behind each answer.

One app, seven exams. Choose yours and change it whenever you want:

• CNU — Unified National Exam: 954 questions (FGV 2025 and Cesgranrio 2024), all with explanations
• Federal Police: 2,856 True/False questions from Cebraspe (2018, 2021 and 2025 editions), 2,777 with explanations, by position
• Transpetro: 1,728 questions from Cesgranrio (PSP 2023), 1,727 with explanations, in the 41 emphases of higher and middle levels
• Banking: 786 questions from Cesgranrio (Banco do Brasil 2022 and Caixa 2024), all with explanations, including the national and Rio Grande do Sul exam booklets
• DATAPREV: 422 questions from FGV (2024 edition), all with explanations, in General Knowledge and in the 13 profiles

There are 6,963 official questions in total, 6,883 of them with explanations showing the reasoning — why the correct answer is right and where each distractor fails. The explanations are generated with the support of artificial intelligence and checked against the official answer key; the app notifies you of this for each question.
