How to study for a concurso publico starting from zero

Studying for a concurso from zero starts with picking one specific cargo, not a vague category of “concurso publico,” reading that cargo’s edital in full for its syllabus and weighting, and then building a repeating study cycle around whatever the exam actually rewards. Most first-time candidates skip straight to buying course material before doing any of this, which is exactly why so much study time gets wasted on subjects that barely appear on the actual exam.

What is the first thing to do before opening any book?

Pick the cargo, not the exam brand. “I want to study for concurso” is not a plan, because different cargos inside the same concurso can have completely different syllabi, weightings and difficulty. Read the edital’s programa (syllabus) and its quadro de provas (the table listing how many questions each subject gets and how each is weighted) before deciding what to study, because that table is the actual blueprint for where your hours should go, not a generic ranking of “important subjects” from a cursinho’s marketing page.

How should study time be split across subjects?

Roughly in proportion to how the edital weights each subject, adjusted for your own baseline in each one. A subject worth 20 of the 90 questions on a CNU-style objective exam deserves noticeably more hours than one worth five, and a subject you already know well from your degree or your job deserves fewer hours than one you are starting cold, even if both carry the same weight on paper. Building a weekly schedule around the edital’s own weighting table, then adjusting it by your personal starting point, beats studying subjects in whatever order feels most comfortable.

Does a study cycle actually need to repeat, or is a straight-through plan better?

It needs to repeat. A straight-through plan, covering each subject exactly once and moving on, works against how memory actually degrades over months of preparation, because material studied early gets forgotten by the time the exam arrives unless it comes back around. A cycle that rotates through every subject on a fixed schedule, revisiting each one at intervals rather than finishing it once and never returning, is the standard structure serious concurso candidates and most cursinhos converge on, precisely because it matches how retention actually works over a preparation that can run a year or more.

How much does the actual exam date change the plan?

It changes everything about pacing. A candidate with eight months until the prova can afford a longer first pass through the full syllabus before shifting into revision-heavy cycles; a candidate with six weeks cannot, and needs to prioritize ruthlessly by weighting and personal weak points instead of trying to cover everything. Track the actual date rather than a rough mental estimate, using the exam countdown tool, because the studying strategy that works with six months of runway is a different strategy from the one that works with six weeks, and using the wrong one wastes exactly the time you cannot afford to waste.

Should someone starting from zero go straight for a demanding cargo like CNU or start smaller?

That depends on your actual timeline and risk tolerance more than on some rule about starting small. Preparing for a broad, multi-cargo selection like the CNU, whose bloco and cargo structure covers a wide range of posts and difficulty levels under a single national exam, can be a reasonable entry point precisely because it gives you multiple shots inside one preparation cycle. A narrower cargo like TJ-SP escrevente, with a more concentrated syllabus, can also be a sound first target if the career fits what you want and the syllabus is short enough to master in the time you have.

Is studying alone, without a cursinho, viable from zero?

Yes, for many cargos, though it demands more discipline in building your own weighted schedule since nobody hands you one. We cover the specific trade-offs of self-study versus a paid course in studying for a concurso without a cursinho, including which specific ingredients a self-taught plan needs to replace what a course otherwise provides automatically.

Frequently asked questions

How many hours a day should someone studying from zero commit? There is no universal number, since it depends on your timeline against the syllabus size and your baseline knowledge. What matters more than the daily total is consistency across weeks, since a study cycle only works if you actually complete each rotation rather than skipping around.

Should I start with theory or with practice questions? Most effective plans alternate: a first pass of theory per subject, followed quickly by practice questions on that same subject before moving to the next, rather than finishing all theory across every subject before touching a single question.

Is it a mistake to study every subject equally? Yes, if the edital’s weighting table shows subjects are not weighted equally, which is nearly always the case. Equal time across unequally weighted subjects means under-investing in what the exam actually rewards most.

How do I know if my pace is on track for the exam date? Compare how much of the full syllabus rotation you have completed against how much time remains until the confirmed prova date, adjusting your daily targets whenever that ratio starts slipping rather than waiting until the final weeks to notice.

Does starting from zero mean I need a diagnostic test first? It helps. A diagnostic pass, even an informal one using past exam questions for your target cargo, tells you which subjects genuinely need a full first pass and which ones you can move through faster because you already have a baseline.
