STJ - Analista Judiciário · Understand the traps and how to avoid them.
Reading a Portuguese interpretation question and answering from memory of the text instead of locating the exact passage that supports or refutes each option, so the chosen alternative reflects the general theme rather than the specific wording of the item.
Interpretation items are written so that two or three alternatives are plausible at the level of general meaning; only one is anchored in a specific word, connector, or syntactic structure of the text. Candidates under time pressure read the stem and the first lines of the passage, then pattern-match, which is exactly the trap the item constructor designed.
What to do instead
Adopt a fixed procedure for every interpretation item: read the stem first, then read the passage once for global sense, then return to the passage and underline the line that justifies or eliminates each alternative before choosing. For items asking about inference, explicitly mark which alternatives require information absent from the text. Practice on 20 items per session and record, for each wrong answer, which line of the text would have eliminated it.
Treating textual cohesion and rewriting questions as a search for the alternative that 'sounds better', substituting connectives or pronouns without checking whether the logical relation (cause, concession, conclusion, contrast) and the referent are preserved.
Candidates often know the meaning of a connective in isolation but not its argumentative function in context; substitution items are built precisely around connectives whose meanings overlap partially (e.g. contrast versus concession). Because the substituted sentence remains grammatical, the error is invisible to the ear.
What to do instead
Build a personal table of connectives grouped by logical relation and rehearse substitutions in both directions (which connectives can replace X, and which change the relation). For pronoun and ellipsis items, always identify the referent by asking 'who exactly performs this action?' and check number and gender agreement. Verify that the rewritten passage keeps the same truth conditions as the original.
Answering constitutional items by invoking the literal text of the Constitution while ignoring consolidated Supreme Court case law and the binding effect of general repercussion theses and binding precedents (súmulas vinculantes).
Many constitutional rules are open-textured, and the exam expects the candidate to know how the Supreme Court has settled contested readings. Candidates who studied only the constitutional text believe the literal wording is decisive and do not check whether a settled thesis has narrowed or expanded it, which is common in items on fundamental rights, federalism, and judicial review.
What to do instead
For each constitutional topic in the syllabus, attach the leading Supreme Court decision or thesis to the article. Maintain a one-page sheet per theme with three columns: constitutional text, settled case law, and exceptions. Review the sheet before practising items so that the case-law layer is active while you read the alternatives.
Confusing the regimes of administrative acts - annulment versus revocation, ex officio review (autotutela) versus judicial review, and the effects of convalidation - and applying the wrong remedy to the fact pattern presented.
These concepts share vocabulary and are taught together, so they blur in memory. Items exploit this by describing a perfectly valid act that has become inconvenient (which calls for revocation, not annulment) or an act with a curable defect (which calls for convalidation, not annulment). Candidates match on keywords such as 'illegality' without checking whether the defect is in the act or in the situation.
What to do instead
Draw a decision tree: is the defect one of legality or of merit? If legality, is it curable? If curable, convalidation; if not, annulment with retroactive effects. If merit, revocation with prospective effects. Add the limits: acquired rights, time limits for annulment, and the difference between administrative and judicial review. Redo the tree from memory before each practice block.
Missing procedural deadlines and counting rules in civil procedure items - starting the count from the wrong event, ignoring that only business days count, and forgetting the different treatment of electronic and physical filings.
Deadline items require chaining several rules: the legal or judicial term, the starting point (publication or availability of the decision in the electronic system), the exclusion of the first day and inclusion of the last, and the extension or suspension rules. Candidates who memorise only the number of days in the Code fail when the item asks about the starting point or about a specific procedural posture.
What to do instead
Practise by solving small timeline scenarios: given a decision published on a date, compute the term in business days, identify the last day, and state what happens if it falls on a court recess or holiday. Write out the chain of rules once per week, and always check the item's wording for whether it asks about the term itself, its starting point, or its effects.
Applying general civil law rules to fact patterns that are governed by a special regime, such as consumer relations, and therefore missing the inversion of the burden of proof or the objective liability standard.
The general civil law regime and the consumer protection regime coexist, and candidates default to the general regime because they studied it more. Items deliberately describe a supplier-consumer relationship to test whether the candidate recognises the applicable statute and its consequences.
What to do instead
Before answering any civil law item, classify the relationship: is there a consumer, a supplier, a service provider, a contract of adhesion, or a risk activity? Then select the regime. Keep a comparison sheet of liability standards (subjective, objective, strict for risk) and burden-of-proof rules across the Civil Code and the Consumer Protection Code, and review it before each civil law block.
Confusing the internal rules of the court with the general procedural law when answering questions about the court's internal regiment - attributing to the full court, to a panel, or to the president powers that belong to another body, or misstating the composition and competence of internal organs.
The internal regiment uses terms that overlap with the Code of Civil Procedure, and the allocation of competences among the plenary, the special court, the panels, and the president is detailed and easy to conflate. Candidates often study it last and only superficially, relying on intuition about how a court 'should' be organised.
What to do instead
Build an organ-by-organ matrix: for each internal body, list its composition, its competences, and the appeals or incidents it decides. Test yourself by covering columns and reconstructing them. Pay special attention to items describing a concrete procedural situation and asking which organ decides it, since these require applying the matrix rather than reciting it.
Answering computer and electronic process items from everyday software intuition rather than from the specific rules of the electronic judicial process and the security concepts in the syllabus, such as digital certification, electronic signature, and the validity of electronic documents.
The syllabus mixes general computing notions with procedural rules on electronic filing, and candidates who are comfortable with technology assume their habits transfer. Items test precise legal-technical definitions, for example what confers authenticity and integrity on an electronic document, or who may certify it.
What to do instead
Separate the two layers explicitly: technical concepts (network, storage, backup, malware, encryption, certification) and procedural rules (filing, consultation, deadlines in the electronic system). Create flashcards for each definition with a concrete example, and for procedural items always ask which rule of the electronic process statute applies before reasoning from general practice.
Solving logical reasoning items by reading the statements once and reasoning informally, without translating premises into a structured notation, which leads to accepting conclusions that are merely plausible rather than logically entailed.
Verbal reasoning feels easy, so candidates skip the translation step. But items with conditional statements, quantifiers, and syllogisms punish informal reading: conversational implicature suggests conclusions that do not follow, and the candidate cannot identify the exact step where the inference broke.
What to do instead
Standardise every item: write conditionals as implication arrows, negate the consequent to test validity, and for syllogisms draw a quick diagram of sets. For each wrong alternative, state in one sentence why it does not follow (converse error, affirming the consequent, undistributed middle). Do timed sets of ten items and review only the reasoning structure, not the content.
Mismanaging time across the paper by spending too long on the first language and reasoning items, then rushing the procedural and internal regiment blocks, and guessing on items that were solvable with thirty more seconds.
The paper mixes domains of very different difficulty per item, and candidates tend to allocate time by order rather than by expected yield. Early items feel tractable, so the candidate keeps polishing them, not noticing that the later blocks contain many short, high-confidence items that are being sacrificed.
What to do instead
Before the exam, define a per-block time budget and a rule for abandoning an item after a fixed interval. During practice, simulate the full paper with a clock and mark items you abandon with a symbol so you can return to them. Review the record afterwards: compute how many points were lost in the last block versus the first, and adjust the budget until the loss is balanced across blocks.
