PUC-SP Vestibular common mistakes
PUC-SP Vestibular · Understand the traps and how to avoid them.
Reading the intertextual reference in a poem or advertisement as mere decoration and answering only about the surface topic, ignoring the quoted or parodied source text.
Candidates from technical backgrounds often trained reading for literal information only; intertextuality demands recognizing the prior text and the new meaning produced by the clash, which requires cultural repertoire they may not have consolidated.
What to do instead
Before answering, explicitly write in the margin: 'source text says X, new text reuses it to say Y, effect = Z'. Practise with parodies of famous poems and ads that quote classics, always stating the shift in meaning, not just identifying the source.
Treating 'variedade linguística' questions as right/wrong grammar and choosing the option that calls a regional or popular variant 'incorrect' or 'inferior'.
School grammar teaching still frames norms prescriptively, and candidates transfer the idea that only the standard norm is valid, missing the sociolinguistic principle of adequacy to context.
What to do instead
Memorize the operative concept: variants are adequate or inadequate to a communicative situation, not correct or incorrect. On every such question, ask 'who speaks, to whom, in what situation' and eliminate any option containing value judgments about the speaker's intelligence or language.
In literature questions, confusing the narrator with the author or summarizing the plot instead of analysing the requested literary procedure (focus, time, irony, symbolism).
Exam pressure leads to answering what is easy to recall (the story) rather than what was asked (the technique), and the author/narrator conflation is a persistent school-level gap.
What to do instead
Underline the command verb in the question ('identify the narrator's focus', 'explain the irony') and answer only that. Train by taking a short story and writing two separate columns: 'what happens' versus 'how it is told'.
In history and geography items, picking the alternative that contains true isolated facts without checking whether it actually explains the phenomenon posed in the command.
Alternatives are built with plausible true statements as distractors; candidates recognize a familiar date or concept and stop there, failing to test the causal link demanded by the question.
What to do instead
Apply the 'true but irrelevant' test: for each option, ask 'does this answer the question asked?'. Reject options that are historically accurate but do not establish the requested relation (cause, consequence, comparison).
Reading maps, graphs, and cartograms impressionistically ('the line goes up') without extracting axes, units, scale, period, and source before interpreting.
Graphic literacy is often undertrained; candidates jump to the visual trend and ignore that the vertical axis may start at a non-zero value, that the scale is logarithmic, or that the period is short and unrepresentative.
What to do instead
Adopt a fixed protocol before interpreting any graphic: title, source, axes and units, scale, period, legend. Only then describe the trend in words and compare it with the options.
In physics and chemistry items, substituting numbers into a formula immediately, without converting units to the SI and without identifying the system and the principle involved.
Formula-driven study habits and time pressure encourage 'number hunting'; mixed units (g and kg, cm and m, minutes and seconds) then produce an answer that matches a distractor.
What to do instead
Write a three-line plan before calculating: principle (e.g., conservation of energy), known quantities with units converted, unknown to be found. Estimate the order of magnitude first so an absurd result is caught.
In biology, answering about a process (photosynthesis, meiosis, immune response) by recalling a memorized phrase without checking the stage or condition specified in the stem.
Content is learned as isolated labels rather than as a sequence with inputs and outputs, so candidates cannot locate where in the process the question sits.
What to do instead
Build flow diagrams for the core processes with inputs, outputs, and location for each stage, and rehearse 'where in the process is this?' before reading the options.
In mathematics, solving the equation found in the stem but not returning to the question's actual demand (e.g., the maximum instead of the value that produces it, the total instead of the monthly amount).
The algebra consumes attention and the final reading of the command is skipped; distractors are deliberately built from intermediate results.
What to do instead
After obtaining a numerical result, re-read the question and label the answer ('this is x, they asked for 2x + 3'). Also test the result against the problem's constraints and plausible magnitude.
In quantitative items, choosing an answer by visual approximation of a figure or by 'it looks proportional' instead of establishing the geometric or algebraic relation explicitly.
Figures in exams are illustrative and not to scale, but candidates treat them as measured data; proportion intuitions also fail with areas and volumes, which scale differently from lengths.
What to do instead
Redraw or annotate the figure with the given data only, mark what is unknown, and write the governing relation (similarity, Pythagoras, area formula) before computing. Remember that areas scale with the square and volumes with the cube of the linear factor.
In the redação, presenting a generic solution ('the government must invest more and raise awareness') disconnected from the specific problem, and ignoring the required structural elements of the proposal.
Candidates memorize ready-made closing formulas and lack repertoire about concrete public policies and agents, so the intervention does not name who acts, how, and with what effect.
What to do instead
Build a repertoire bank of concrete agents and instruments (ministries, agencies, school curricula, media regulation, NGOs) and, for each essay, draft the proposal with four explicit elements: agent, action, means, and expected outcome, tied to the causes argued in the development.
