UFSC Vestibular common mistakes
UFSC Vestibular · Understand the traps and how to avoid them.
Memorizing isolated formulas from Física and Matemática without knowing the conditions under which each applies, then applying a formula to a situation where its hypotheses fail (e.g., using uniform-motion equations for accelerated motion, or Ohm's law outside a purely resistive context).
The programmatic content is broad and candidates often study by listing formulas rather than by studying the physical or mathematical model each formula represents; under time pressure they pattern-match on keywords instead of checking validity conditions.
What to do instead
For each formula, write a one-line 'contract' stating its hypotheses and units, and solve at least three problems per topic where you first justify why the formula applies before substituting numbers. Build a personal sheet pairing each formula with a counterexample where it does not apply.
Reading a Portuguese-language question stem quickly and answering the remembered topic rather than the actual command, ignoring negation words ('exceto', 'incorreto', 'não') and restrictive qualifiers ('apenas', 'somente', 'sempre').
Vestibular stems are long and dense; candidates skim to save time and their prior knowledge activates a familiar answer before the exact request is parsed, especially on multiple-choice items where the first plausible option feels correct.
What to do instead
Adopt a two-pass routine: first pass, underline the command verb and any negation/restriction and restate the question in your own words in one sentence; second pass, evaluate options. Train by re-doing 20 previously answered questions focusing only on identifying what is being asked, not on solving.
Treating intertextuality and discourse-level interpretation in Português/Literatura as personal opinion, choosing the option that matches the candidate's own view of the theme instead of the textual evidence.
Interpretive items require locating the author's argument, tone, and rhetorical strategies, but candidates answer from general impressions of the topic and from the excerpt's subject matter rather than from how it is said.
What to do instead
For every text, annotate thesis, argumentative moves, tone markers, and connectives before looking at the options; then require each chosen option to be justified by a quoted fragment. Practice with a fixed annotation grid so the habit becomes automatic.
Solving História and Geografia items with present-day intuition or moral judgement rather than with the specific historical or geographic context requested (period, region, scale, agent).
These disciplines in the programmatic list emphasize processes, periodization, and spatial scales; candidates often know general narratives but not the specific conjuncture, so they select anachronistic or scale-mismatched answers.
What to do instead
Build a timeline and a set of regional maps for each unit, and for every past question write the period, place, and main agents in the margin before choosing. Drill items by asking 'which scale and which decade is this about?' first.
In Biologia and Química, answering definitional items from everyday meanings of terms (e.g., 'adaptação', 'energia', 'ácido') instead of the technical definition used in the syllabus.
Scientific vocabulary overlaps with common language, and candidates who studied by reading summaries retain the everyday sense; the distractor options are often built precisely on that everyday sense.
What to do instead
Maintain a glossary where each term is defined technically plus one example and one common misconception; before answering, state the technical definition aloud mentally and check which option is consistent with it.
Skipping units and dimensional checking in Física and Química calculations, then selecting a numerically plausible distractor that differs only by a power of ten or a unit conversion.
Under exam pressure candidates substitute values without converting (g to kg, mL to L, km/h to m/s) and without tracking units; distractors are designed to match these unconverted results.
What to do instead
Make unit conversion an explicit written step and carry units through the calculation until the final line. Practice by solving five problems per topic writing units at every stage, and always compare the magnitude of the result with an order-of-magnitude estimate.
Answering Matemática items by inspection or by testing one value, without verifying domain restrictions (denominators, square roots, logarithms, absolute values) and without checking whether extraneous solutions were introduced.
Candidates learn procedures for solving equations but not the equivalence conditions of each step; squaring or multiplying by an expression can create solutions that satisfy the transformed but not the original equation.
What to do instead
End every equation with an explicit verification step substituting the candidate roots into the original equation, and record the domain restrictions at the start. Practice with a set of problems deliberately built to produce extraneous roots.
Writing the redação as a generic opinion essay with a moralizing conclusion, without a thesis, argumentative development, and a proposal of intervention linked to the discussion.
Candidates transfer school essay habits and treat the topic as an invitation to personal reflection; they also run out of time and compress the conclusion into a slogan, losing points on the argumentative structure the exam expects.
What to do instead
Train a fixed four-part architecture (contextualization, thesis, two developed arguments with evidence, intervention with agent/action/means/effect) and write timed essays weekly. Build a repertoire bank of verifiable facts and data across recurring themes so arguments are concrete rather than abstract.
Managing time uniformly across the whole exam, spending too long on a few hard items in the first disciplines and leaving later disciplines (or the redação) rushed or blank.
The exam is long and multidisciplinary; candidates lack a per-section time budget and are reluctant to abandon a problem they have already invested in, a sunk-cost effect that compounds across sections.
What to do instead
Simulate full exams with a written time budget per discipline and a hard rule: if an item is not resolved after its allotted minutes, mark it and move on. Do at least three full timed simulations before the exam and review where time was lost.
Studying the programmatic content as a flat list, giving equal attention to all topics and neglecting the specific weighting and the recurring themes indicated by the program, so high-frequency content is under-practiced.
Without analyzing the programmatic content and past exams, candidates cannot distinguish core topics from peripheral ones and default to studying what feels comfortable or what appears first in textbooks.
What to do instead
Map the official programmatic list against several past exams to tag each topic by frequency and difficulty, then allocate study time proportionally, ensuring every listed topic is at least reviewed once while high-frequency ones receive repeated practice with correction.
