Knowledge Areas & High-Yield Topics
Natural Sciences: Ecology, genetics, human physiology, electrodynamics (circuits & electrical power), wave mechanics, thermal physics, stoichiometry, and organic reactions.
Mathematics: Plane & spatial geometry, linear and quadratic functions, descriptive statistics (mean, median, mode), ratios, proportions, and basic probability.
Languages & Humanities: Reading comprehension, rhetorical analysis, citizenship, modern Brazilian history, geopolitics, philosophy, and sociology.
Essay (Redação): 30-line argumentative essay evaluated across 5 official competencies (up to 1,000 points), requiring a concrete public intervention proposal respecting human rights.
Spaced Repetition (SRS) vs Weekend Marathons (1h30/day)
Avoid exhausting 8-hour weekend cramming sessions that suffer from steep memory decay. Commit to 1h to 1h30 daily using spaced repetition (SRS) with active recall.
Daily micro-reviews interleave Natural Sciences formulas, historical milestones, and sociological quotes, anchoring high-yield concepts into long-term memory before the November test date.
Item Response Theory (TRI) & SiSU Weighting
Item Response Theory (TRI): ENEM scores reward pedagogical consistency rather than raw counts. Answering hard questions correctly while missing easy ones is penalized as random guessing. Always secure every easy and medium question first.
SiSU Course Weights: Federal universities weigh knowledge areas differently per major (e.g., Medicine prioritizes Natural Sciences and Essay; Engineering heavily weights Math). Calibrate your daily review time to match your target university's weighting.
Official INEP Archive: Practice with genuine past questions to master distractor patterns and calibrate to the strict pacing of 3 minutes per question.
