PCSP Delegado de Polícia common mistakes

PCSP Delegado de Polícia · Understand the traps and how to avoid them.

Mistake 1

Memorizing constitutional article numbers and headings without learning the exact wording of the fundamental rights and remedies, then answering questions about habeas corpus, habeas data and mandado de segurança by intuition about what the remedy 'should' cover.

Constitutional law is the largest and most cited block, so candidates skim it early to 'cover ground' and never return to the precise text of art. 5º, LXXII, LXIX, LXXVII and the free/speed provisions; they also confuse collective and individual remedies because they never read the paragraphs.

What to do instead

Build a one-page table for each remedy listing: right protected, legitimidade ativa, procedural vehicle, free or not, deadline, and who can file. Recite the table weekly from memory, then test it against actual case facts (e.g., a request for personal data from a public registry versus a request for correction of that data) and justify the choice in writing.

Mistake 2

Treating the principles of public administration (legalidade, impessoalidade, moralidade, publicidade, eficiência) as a list to recite, and then failing questions that ask which principle justifies a concrete act such as removal of a public servant for nepotism or a publication restriction.

The five-word mnemonic is easy to memorize and gives a false sense of mastery; candidates never practise mapping facts to principles, and they conflate moralidade with legalidade when the act is formally lawful but ethically tainted.

What to do instead

For each principle, write two concrete administrative scenarios and the legal consequence. Practise 'fact to principle to consequence' chains in three sentences, and check the answer against the doctrine of the implicit powers and the self-executing nature of each principle.

Mistake 3

Applying the general rule of penal law without checking the special part or the extravagante statute that actually governs the case, for example answering a drug-trafficking question using the ordinary Penal Code thresholds or ignoring the specific type of the statute.

Candidates study the general part intensively because it is conceptually rich, then treat the special part as a list of article numbers; they also assume that a conduct described in common language maps to the most familiar offence rather than to the specific statute.

What to do instead

For each high-frequency offence, build a card with: legal good, element of the type, subjective element, thresholds or quantities, privileged and qualified forms, and the specific statute that prevails. Rehearse comparisons between similar offences (e.g., theft versus misappropriation versus receiving) and state in writing the exact element that distinguishes them.

Mistake 4

Confusing the procedural consequences of each phase of the criminal process, such as mixing the requirements for flagrante with those for preventive detention, or believing that the conclusion of the investigation automatically ends the custody or the admissibility of evidence.

The procedural code is studied as a sequence of chapters, so candidates learn the rules of each phase in isolation and never build a timeline connecting investigation, accusation, instruction and trial; the deadlines and the competent authority are then recalled loosely.

What to do instead

Draw a single timeline of the process and annotate each measure with its legal basis, competent judge, maximum duration and the consequence of expiry. Work through a hypothetical case from flagrante to sentence, writing one line per step and checking each step's statutory basis.

Mistake 5

Answering civil and civil-procedure questions by general fairness instinct, without distinguishing prescription from decadência, or without identifying whether the question asks about the existence of the right, the procedural time limit, or the effect of the decision.

Civil law concepts are superficially familiar from daily life, which encourages fast intuitive answers; candidates also skip the procedural part because it feels secondary, so they never learn the rules on competence, preclusion and the effects of res judicata.

What to do instead

Create a comparison grid for prescription versus decadência (object, legal basis, interruption, suspension, waiver). For procedure, practise identifying in each fact pattern: the competent court, the applicable procedural regime and the effect of the deadline. Write the legal basis for every answer before choosing the alternative.

Mistake 6

Studying criminology and legal medicine as isolated definitions, then failing questions that require applying a concept to a case, such as classifying a lesion by its nature or interpreting a finding about the time of death, and confusing victimology with the study of the offender.

These are the domains candidates most often leave for the final week, so they memorize short glossaries without ever practising the reasoning that connects a described finding to a classification or a conclusion.

What to do instead

Convert each concept into a decision rule with observable inputs (e.g., type of wound, vitality of the lesion, signs of death). Practise short case vignettes and state the rule you applied. Keep a glossary with one example per term, and review it in spaced intervals rather than in a single block.

Mistake 7

Reading a question about a special statute and answering with the rule of the Penal Code or of another statute that seems similar, because the candidate recognizes the topic but not the precise legal instrument that governs it.

The extravagante legislation is extensive and fragmented, so candidates learn it by topic (drugs, weapons, organized crime) and lose track of which statute supplies each rule, especially where statutes overlap or cross-reference.

What to do instead

Maintain a matrix of statutes by topic, listing for each the conduct, the penalty range, the procedural peculiarities and the organs involved. Before answering, name the statute aloud and verify that the alternative matches that statute's wording, not the wording of a neighbouring law.

Mistake 8

Treating human rights and international law as a set of declarations to be summarized, then missing questions about the hierarchy of treaties in the domestic order, the effect of a condemnatory decision, and the difference between a treaty incorporated by ordinary law and one approved with the special procedure.

The material is read as history and values rather than as binding norms with domestic effects; candidates also confuse the international protection systems and the standing of the individual before each of them.

What to do instead

Build a hierarchy chart of the domestic order with the position of treaties and the consequences of each position. For each protection system, list the instrument, the organ, the admissibility requirements and the type of decision. Practise applying the hierarchy to a concrete conflict between a treaty and a statute.

Mistake 9

In Portuguese language and writing, producing a text that is grammatically acceptable but does not answer the command of the question, and in objective items choosing the alternative that 'sounds better' rather than the one that respects regency, agreement and textual coherence.

Candidates rely on the ear acquired from reading, which fails on rare constructions and on the difference between oral and written norms; in the discursive part they write everything they know about the topic instead of planning the answer around the command and the evaluation criteria.

What to do instead

For discursive answers, spend the first minutes underlining the command verb and the required elements, then outline before writing and verify at the end that every element was addressed. For objective items, identify the syntactic function of the doubtful term and apply the rule explicitly; keep an error log of recurring grammar mistakes and review it before each simulation.

Mistake 10

In logical reasoning and statistics, solving problems by pattern matching on familiar question types and skipping the formalization step, so that a small change in wording (negation, quantifier, conditional direction) produces a wrong answer; in statistics, calculating a measure without checking the assumptions of the data.

Practice with repeated item formats creates recognition instead of reasoning; candidates also avoid writing the symbolic form because it feels slow, and they memorize formulas without understanding when each measure is appropriate.

What to do instead

Force a formalization step: translate every statement into symbols, identify the quantifiers and the direction of the conditional, and only then evaluate. For statistics, before calculating, state the level of measurement and the assumptions; practise interpreting results in words, not only computing them.

Mistake 11

In informatics and institutional legislation, answering from general familiarity with technology or from a vague memory of the institution's rules, without verifying the specific provision about competence, procedure or data protection that the item tests.

These domains feel peripheral and are studied last, so candidates rely on everyday experience with software and on impressions about the institution rather than on the precise text of the statute, the internal regime or the data-protection rules.

What to do instead

Treat both as text-based domains: read the institutional statute and internal regime once in full, then build a table of competences and procedures with the exact article for each entry. For informatics, study concepts by function (storage, transmission, security, backup) and verify each answer against the definition rather than against personal habit.
