Procurador da Fazenda PGFN · Understand the traps and how to avoid them.
Reading a constitutional question and answering from the literal text of the article alone, ignoring consolidated Supreme Court (STF) case law and binding precedent (súmulas vinculantes, ADI/ADPF decisions, repercussão geral theses).
Constitutional law in this exam is tested almost entirely through jurisprudential concretization; candidates memorize the 1988 Constitution's wording from law school and never update it, so they miss that the correct answer reflects a settled STF interpretation that departs from the literal text.
What to do instead
Build a running 'article → leading STF decision → current thesis' map for each tested topic (taxation, administrative improbity, public employment, social security). Before each study block, review the last six months of STF informativos and rewrite your notes so the operative rule is the thesis, not the article.
Treating the legality principle in administrative law as a simple checklist (is there a law?) without distinguishing vinculação (bound competence) from discricionariedade and without applying the modern limits on discretionary choice (razoabilidade, proporcionalidade, motivação).
Candidates learn administrative law as a list of principles and then answer 'the administration may act because it is discretionary' or 'the administration must act because legality is strict', failing questions that test the abuse-of-discretion and motivation doctrines.
What to do instead
For each administrative act in a question, force yourself to state in one sentence: the competence, the form, the motive, and whether the choice is bound or free. Then test the free choice against proportionality and the duty to give reasons. Practice writing this four-line analysis for ten acts per session.
Applying the tax code's general rules to a specific tribute without checking the constitutional allocation of competence and the specific statutory regime (e.g., treating a contribuição de melhoria like a taxa, or applying the CTN's prescription rules to a tribute governed by a special complementary law).
Candidates study the National Tax Code (CTN) as a single unified framework and skim the constitutional tax chapter, so they default to generic rules instead of identifying which entity has competence and which special statute displaces the general one.
What to do instead
Before solving any tax question, write the tribute's name and then three items: constitutional basis, competent entity, and governing special law. Only after that open the CTN. Drill this with a table of the tributes in kind for each federative entity.
Confusing the legal nature and the stages of public revenue and expenditure - treating lançamento (assessment) as the moment of payment, or mixing empenho, liquidação and pagamento - and answering budget questions from common sense rather than the statutory sequence.
Financial law is studied late and superficially; the stages sound administrative and candidates assume they are interchangeable, so questions that turn on which stage creates the enforceable obligation are answered incorrectly.
What to do instead
Memorize the two chains as ordered lists with one defining verb each: receita (previsão → lançamento → arrecadação → recolhimento) and despesa (fixação → empenho → liquidação → pagamento). For every practice question, identify which stage is being described before reading the alternatives.
Ignoring the procedural dimension of a civil-law question - answering who is right on the merits without asking whether the claim is time-barred, whether the correct procedural vehicle was used, or whether the judgment is enforceable - and mixing prescription with decadência.
Candidates separate substantive civil law from civil procedure in their heads, and the exam deliberately crosses them; the hurry to show doctrinal knowledge leads to skipping the preliminary procedural filter.
What to do instead
Adopt a fixed two-pass routine: first pass, identify the procedural posture (parties, vehicle, deadline, preclusion); second pass, analyze the merits. Keep a one-page sheet distinguishing prescription (extinguishes the claim) from decadência (extinguishes the right) and review it before every simulation.
Answering labour questions by importing the general civil limitation periods or the CLT's general rules without checking whether a special rule applies (e.g., the constitutional rule on rural workers' claims, or the specific deadlines for challenging a dismissal), and treating procedural labour rules as identical to the civil code of procedure.
Labour law is often the candidate's weakest area because it is studied last and with borrowed civil-law instincts; the exam exploits exactly that transfer of inapplicable rules.
What to do instead
Maintain a short list of 'where labour departs from civil': limitation periods, burden of proof, the free-of-charge procedural privileges, and the constitutional protection of the employment relationship. Test each new rule by asking 'does the CLT or the Constitution expressly displace the civil rule here?'
Applying substantive criminal-law reasoning to a procedural question (or vice versa) - discussing whether the conduct is a crime when the question asks about the legality of the evidence, or debating the merits when the issue is the statute of limitations or the competence of the court.
Criminal law and criminal procedure are memorized as one blended block, and under time pressure candidates answer the question they find easier rather than the one asked, missing that the procedural defect alone decides the case.
What to do instead
Before answering, underline the interrogative verb in the prompt ('is the evidence valid', 'is the conduct criminal', 'is the court competent') and refuse to write anything outside that verb. Practice with mixed sets where the substantive and procedural answers point in opposite directions.
Reading the Portuguese language section as a vocabulary test and answering interpretation questions from personal impression, without locating the textual evidence (connective, pronoun reference, scope of a negation) that supports the chosen alternative.
Candidates treat the language block as free points and spend little time on it, so they choose the alternative that 'sounds right' instead of the one the text actually supports, losing points that are cheaper than any legal topic.
What to do instead
For every interpretation question, write beside each alternative the line of the text that confirms or refutes it; discard any alternative you cannot anchor to a specific passage. Do twenty such questions weekly and review only the ones you missed, classifying the error as reference, connective, or scope.
Managing time as if all questions were equal - spending many minutes on one hard tax or constitutional question early, then rushing the language and labour blocks and guessing the final items.
The exam mixes long doctrinal questions with short interpretative ones; candidates without a per-block time budget let the sunk-cost of one difficult item consume the time needed for several easy ones.
What to do instead
Set a per-block time cap before starting and a hard skip rule: if a question is not resolved after its allotted time, mark it and move on. Reserve the last fifteen minutes for marked items and for checking that no answer sheet field was left blank.
Studying by reading summaries and statutes passively, without producing answers under exam conditions, so the candidate recognizes a rule but cannot apply it to a novel fact pattern within the time limit.
Recognition feels like mastery; rereading notes creates familiarity that collapses when the exam requires retrieval and application to facts the candidate has not seen.
What to do instead
Invert the ratio: for every hour of reading, spend two hours writing full answers to past-style questions and then correcting them against the statute and case law. Keep an error log with the rule missed and the reason, and re-test only the logged items every two weeks.
