Nefai: Vestibular e ENEM

The exam is approaching, and that feeling of "Am I studying enough?" just won't leave your head? Breathe. Nefai exists to transform that anxiety into consistency—a little bit every day, the way it works.

EXAM QUESTIONS, WITH SOURCE
Thousands of questions from previous exams—FUVEST, ENEM, PUC-Campinas, FGV, Unicamp, Insper, and FMABC—each with the identification of the original exam, reproduced faithfully to the original: the bold text, the tables, the formulas, and the images in the place where they appear in the exam. Tap any image to enlarge it. In addition, there are original questions in the style of each exam board, always identified as original within the app.

SIMULATED EXAMS LIKE ON EXAM DAY
Take complete past exams, in the order and time of the exam board, with the clock running. And, when you want to practice a specific point, create your own set by subject.

MADE A MISTAKE? TURNED THE DIRECTION
Instant feedback on every answer. Your mistakes become a chance for revenge: Nefi separates the questions that tripped you up so you can try again. And everything you answer is saved in your history — you can filter out only the mistakes and go back to the question.

HIGHLIGHT LIKE ON PAPER
Select the important part of the question and it gets highlighted — and remains highlighted when you return to that question.

THE RIGHT PATH FOR YOUR EXAM
Choose your path — FUVEST, ENEM, PUC-Campinas, FGV, Unicamp, Insper, FMABC or VUNESP, which brings together the exams administered by that organization — and study with questions aligned with the format and content of that entrance exam. The subject grid changes along with it: you only see what your organization requires.

START SMALL, DON'T STOP
No time? The quick 3-question mode fits into any interval of the day. And the daily sequence transforms "study tomorrow" into a habit you won't want to break.

SEE YOUR PROGRESS HAPPEN
Detailed performance by subject and subtopic: you know exactly where you're strong and where you need to review. Less guesswork, more direction.

NEFI IS WITH YOU
Nefi, our little mascot cloud, accompanies your journey, celebrates your achievements, and gives you a nudge when you disappear. And your sequence paints the sky of your profile: with each milestone it changes — from sunrise to 7 days to the Milky Way. Here, nobody studies alone.

STUDYING TOGETHER IS EASIER
Add friends, see who's online to study together, and create study groups with a wall and weekly goal. There are over 270 achievements to unlock, each with its own celebration — and your favorites are showcased on your profile. Consistency is contagious.

QUESTION DUEL
Challenge a friend to a 10-question duel, 1v1 or 2v2. Each person answers at their own pace, and at the end, you see who got more right, question by question.

YOUR WAY
Dark mode and optimized interface for Android phones and tablets.
