Brazil’s Enem, the National High School Exam, will be held on November 8 and 15. Students preparing for the test can use free online mock exams to review content, assess their performance and identify topics that require more attention.
Luzia’s Preparador Enem is an in-app study tool available on Android and iOS through the assistant’s Create section. It brings together 1,675 official questions from Inep, detailed essay correction and an adaptive study plan, without requiring a separate registration. Its artificial intelligence feature provides the correct answer and explains what was wrong with the specific alternative selected by the student.
Another option is Projeto Aprovação, from Plataforma AZ. The free platform offers mock exams, previous tests, essay tips, study planning and content for the Enem, Fuvest and other university entrance exams, including those of Unicamp, Unesp, UnB and UFSC. Its 2026 edition includes videos and tools designed for different selection processes.
The project’s Rota da Aprovação helps students organize their study routine until exam day and also addresses emotional factors that may affect candidates as the tests approach. The Rota de Vestibulares allows users to adapt their preparation to the exam they intend to take, with recurring topics, past tests, required books, information from different exam notices and teacher-led videos. The platform also provides essay guidance and possible topic suggestions.
AMentoria, an edtech focused on university entrance exams, offers another free Enem mock exam. The tool reproduces the test format, allows students to practice under time constraints and assesses performance in the four knowledge areas covered by the exam. After completing the questions, users can review their mistakes and focus their studies on identified weaknesses.
The platform also applies Item Response Theory to estimate scores in each area, taking into account factors such as question difficulty and the consistency of the answer pattern. The mock exam is divided into two independent days, with 90 questions on Languages, Codes and their Technologies and Human Sciences and their Technologies on the first day, followed by 90 questions on Mathematics and its Technologies and Natural Sciences and their Technologies on the second. The questions are unpublished and prepared by the platform’s teaching team.
Each stage follows the official exam duration: five and a half hours on the first day, including the essay, and five hours on the second. The tests can be taken on a computer or mobile phone, with free access after registration.
The COC education system, part of Arco Educação, provides the Jornada Vestibulares COC platform for students in the final weeks of preparation. It includes a study schedule, material to expand essay references and explanations of subjects frequently tested in the Enem.
Its Raio X da Questão section features short videos in the four knowledge areas, with teachers discussing and solving questions on recurring topics. After the exam, students will also be able to access the answer key and a SiSU calculator to estimate their chances of admission.
