Answering constitutional questions by quoting article numbers from memory without checking whether the literal text of the provision actually resolves the concrete case presented (e.g., applying the literal wording of art. 5º, XI, on inviolability of the home, to a flagrante delito scenario without considering the STF's concrete delimitation of the exception).
Constitutional law is studied by memorizing the CF/88's structure and article numbering, so candidates recognize a provision and stop reasoning once the article is identified. The exam, however, tests concrete application and jurisprudential qualification of the text, and the literal wording is frequently insufficient or misleading in the specific hypothesis.
What to do instead
For every constitutional question, state the applicable rule, then explicitly ask 'does the literal text resolve this concrete case, or do I need the STF/STJ qualification?'. Build a personal list of the ~40 constitutional provisions whose application is judicially qualified (inviolability of home, freedom of expression vs. hate speech, right to silence, habeas data, etc.) and, for each, record the concrete delimitation, not just the article number.
Treating administrative-law principles (legalidade, impessoalidade, moralidade, publicidade, eficiência, and the implicit ones) as abstract slogans to be recited, instead of using them as decision rules that determine the outcome of a concrete case involving a public agent's conduct or an administrative act's validity.
Principles are learned as a memorized list for direct questions, and candidates do not practice applying them to fact patterns. When the question presents a factual scenario and asks whether the act is valid, the candidate cannot convert the principle into a legal consequence (nullity, annulment, sanction, duty to motivate).
What to do instead
Practice converting each principle into a testable question: legalidade - is there a legal basis and does the act exceed it?; impessoalidade - was there a personal motive or promotion?; moralidade - does the conduct violate probity even if formally legal?; publicidade - was there unjustified secrecy?; eficiência - was there a measurable performance failure? For each fact pattern, write the principle, the test, and the consequence (nullity, annulment, sanction).
In civil and business law questions, applying the Civil Code's general rules without checking whether a special statute (Lei 6.404/76, Lei 11.101/2005, Lei 8.245/91, CDC, Lei 9.514/97) displaces them, and without verifying the temporal validity of the provision on the date the facts occurred.
Candidates study the Civil Code as the default and treat special statutes as separate topics, so they do not run a conflict-of-norms check. The exam deliberately places facts in a special regime (e.g., a bank's fiduciary alienation, a company's reorganization) where the general rule does not apply or applies only subsidiarily.
What to do instead
Before answering, identify the legal relationship (credit, guarantee, company, contract, real estate) and ask: is there a special statute governing this relationship? Build a one-page 'displacement map' for each area listing the special statute and what it overrides. Also always check the date of the facts against the statute's vacatio legis and any transitional rules.
Answering civil-procedure questions about nullities, preclusion, and procedural deadlines by relying on general notions of 'harmless error' or 'fairness' instead of identifying the specific procedural regime (nulidade relativa vs. absoluta, preclusão temporal/consumativa/lógica, prazo próprio vs. comum) and the exact consequence the CPC assigns.
Procedure is studied as a narrative of the process rather than as a system of typed defects and typed consequences. Candidates know the concepts exist but cannot classify the defect in the concrete case, and so they choose an answer that feels fair rather than the one the CPC mandates.
What to do instead
Build a classification table: for each defect type, record who can argue it, at what moment, whether it is sanável, and the consequence (nullity of the act only, nullity of subsequent acts, or no consequence). Do the same for preclusion types and for the distinction between prazos próprios and comuns. Practice classifying the defect before evaluating the answer options.
In labor and labor-procedure questions, applying CLT rules without checking whether the fact pattern falls under a special regime (bank employee's jornada, categoria diferenciada, teletrabalho, empregado doméstico, servidor público) or whether the reform's transitional rules apply to contracts formed before the reform.
Candidates learn the CLT as a single uniform body and do not internalize that the exam's typical fact pattern (a bank employee) triggers specific rules on jornada, intervalos, and função de confiança. They also forget that the 2017 reform's substantive changes do not retroact to pre-existing contracts.
What to do instead
Create a 'special regimes' sheet for labor law listing bank employees, financiários, domésticos, teletrabalho, and intermitentes, with the specific rule that departs from the general CLT. For every fact pattern, first identify the category and the contract's start date, then select the rule. Practice with questions where the same facts yield different answers depending on the category or date.
In criminal and criminal-procedure questions, confusing the roles of the police inquiry and the prosecution's evidence, and answering questions about prova ilícita, cadeia de custódia, or nulidades by invoking the general principle of 'truth' rather than the specific exclusionary rule and its exceptions (fonte independente, descoberta inevitável, boa-fé).
Candidates study criminal procedure as a sequence of acts and do not grasp that the admissibility of evidence is governed by typed exclusionary rules with typed exceptions. They therefore choose the answer that maximizes evidence rather than the one the CPP and STF jurisprudence require.
What to do instead
For each evidence issue, run a three-step test: (1) is the evidence illicit, merely irregular, or lawful? (2) if illicit, does an exception apply (fonte independente, descoberta inevitável, boa-fé)? (3) what is the consequence (exclusion, nullity, or validation)? Memorize the cadeia de custódia requirements (arts. 158-A to 158-F CPP) as a checklist and apply it to fact patterns involving seized digital devices and bank records.
In tax-law questions, deciding the case on the basis of the tax's name or the taxpayer's characterization instead of applying the materiality principle (art. 118 CTN) and the constitutional limits on competence, and failing to check whether the specific tax's regime (e.g., IOF, CIDE, contribuições) has a special constitutional or statutory rule.
Candidates memorize tax names and rates but do not practice recharacterizing facts. The exam frequently presents a transaction whose legal form differs from its economic substance, and the candidate answers based on the form chosen by the parties rather than on the materiality of the taxable event.
What to do instead
For every tax question, identify: (1) the competent entity under the CF/88; (2) the material taxable event as defined in the CF/88 and the CTN; (3) whether art. 118 CTN permits disregarding the parties' form; (4) the specific constitutional limits (legalidade, anterioridade, irretroatividade, capacidade contributiva). Practice by recharacterizing fact patterns (e.g., a 'service' contract that is actually a lease) and applying the materiality principle explicitly.
In social-security questions, applying the RGPS general rules without checking whether the insured falls under a special regime (servidor público, militar, professor, segurado especial, trabalhador rural) or whether the benefit's calculation must use the correct period and the correct transitional rule (e.g., EC 103/2019 transition rules).
Candidates study the RGPS as the default and treat special regimes and transitional rules as footnotes. The exam's fact patterns often involve a bank employee who is an RGPS insured but whose benefit calculation depends on the date of filiação and the applicable transition rule, and candidates apply the wrong regime or the wrong version of the formula.
What to do instead
Build a decision tree: first classify the insured (RGPS, RPPS, militar, segurado especial), then the benefit, then the applicable temporal rule (pre- or post-EC 103/2019, with the transition options). For each benefit, record the calculation formula with the exact variables and the date from which each version applies. Practice with fact patterns that state the filiação date and require selecting the correct formula.
In international public and private law questions, answering by general principle (sovereignty, comity, pacta sunt servanda) without identifying the specific norm of the applicable convention, the conflict-of-laws rule of LINDB, or the STF/STJ precedent on the hierarchy of treaties (e.g., human-rights treaties with constitutional status vs. ordinary treaties).
International law is studied as a set of principles rather than as a hierarchy of sources with typed effects in domestic law. Candidates therefore cannot determine whether a treaty prevails over a statute, whether it has supra-legal or constitutional status, or which law governs a cross-border contract.
What to do instead
Build a hierarchy chart: treaties on human rights approved by the art. 5º, §3º procedure (constitutional status), other human-rights treaties (supralegal), ordinary treaties (legal status), and the LINDB conflict rules for private law. For each question, identify the source, its rank, and the applicable conflict rule before evaluating the options. Practice with fact patterns involving cross-border contracts and foreign judgments.
In questions on BCB and financial-system legislation, answering from general knowledge of banking rather than from the specific norm (Lei 4.595/64, Lei 7.730/89, Lei 13.506/2017, Resoluções CMN/BCB) and confusing the competences of the CMN, the BCB, and the CVM.
Candidates treat financial-system law as general banking culture and do not memorize the allocation of competences among the CMN, BCB, CVM, and SUSEP, nor the specific sanctioning regime of Lei 13.506/2017. The exam tests precisely these allocations and the procedural guarantees in sanctioning proceedings.
What to do instead
Build a competence matrix: for each authority (CMN, BCB, CVM, SUSEP), record its normative, supervisory, and sanctioning powers and the legal basis. Separately memorize the sanctioning types and the process of Lei 13.506/2017 (including the opportunity to present defense and the possibility of settlement/compromisso). Practice with fact patterns that require identifying which authority is competent and which sanction applies.
