CESPE/CEBRASPE Strategy
The CESPE exam format is unique and requires a specific strategy:
- Negative marking: Only mark an answer if you're at least 70% sure. Leaving blank scores 0; wrong answers score -1.
- Textual interpretation: CESPE questions are statements that may be correct or incorrect. Read carefully for absolutes ("always," "never") which are often wrong.
- Literal vs. interpretive: Distinguish between questions testing literal law text vs. doctrinal interpretation.
- Incomplete is not wrong: In CESPE, an incomplete statement is not necessarily incorrect unless it's misleading.
Flashcard Strategy for PRF
- CTB articles: Create flashcards for key articles of the Codigo de Transito Brasileiro. Focus on infractions, penalties, and categories.
- Crime classifications: Distinguish between crimes dolosos/culposos, tentativa, consumacao for traffic-related crimes.
- Constitutional articles: Art. 5 (fundamental rights), Art. 144 (public security), Art. 37 (public administration).
- Traffic violations: Flashcards for severity (leve, media, grave, gravissima), point values, and fine amounts.
- Special legislation: Drug trafficking law (11.343/06), Disarmament Statute (10.826/03), Abuse of Authority.
