Everything you want to know about Sabero and the ICFES Saber 11

Sabero is a Colombian ICFES Saber 11 exam preparation platform with 10,000+ official-format questions, a per-question AI tutor, a personal AI coach, timed mock exams, Item Response Theory (IRT) score estimates, and detailed analytics by subject. It is available in Spanish and English and requires no credit card to start.

Sabero is designed for Colombian 10th and 11th grade students preparing for the ICFES Saber 11 exam, and also for students who want to improve their score on a second attempt.

Sabero is a Colombian platform built specifically for the ICFES Saber 11 exam. The content, questions, and system context are designed for the Colombian education system.

Sabero stands out on three fronts: the AI tutor that explains each question step by step without giving the direct answer, the IRT score estimate —the same methodology as the official ICFES— and the AI coach that personalizes the study plan based on the student's history.

Sabero's AI tutor activates inside the exam and explains each question step by step with mathematical and conceptual reasoning. It does not reveal the direct answer: it guides the student to discover it through questions, concept explanations, and step-by-step reasoning. It supports unlimited follow-up questions and responds in Spanish or English depending on the configured language.

Sabero's AI coach is a personal advisor that knows the student's full history: exams taken, scores, subject accuracy, and error patterns. It recommends which exams to take, helps plan study before the ICFES, and answers platform questions. The plan updates automatically after each completed exam.

Sabero's AI tutor does not give the direct answer. Its role is to guide the student to discover it through questions, concept explanations, and step-by-step reasoning, reinforcing real learning instead of memorizing answers.

The AI tutor is available in every exam mode in Sabero, including timed mock exams. It activates with a single click on the current question and does not interrupt the exam timer.

Sabero's AI coach recommends a study plan based on the student's current performance, the subjects with the most room for improvement, and the ICFES exam date. The plan updates automatically after each completed exam.

Sabero's questions follow the official ICFES Saber 11 format: reading contexts, four answer options, and the five exam subjects —Critical Reading, Mathematics, Social Studies and Citizenship, Natural Sciences, and English. The questions are original, not leaked from previous official exams.

Sabero can generate AI variations of any question from the question view. Each variation keeps the same topic, difficulty, and format but poses a completely different scenario —ideal for practicing a concept without repeating the same question.

Sabero's bank has more than 10,000 questions in ICFES Saber 11 format. On top of that, the AI can generate new variations of any question, making the bank effectively unlimited.

Every question in Sabero has a detailed AI-generated explanation that covers not only the correct answer but also why the other options are incorrect. Explanations are available after answering each question.

Sabero's exam builder lets you pick subject, difficulty level, number of questions, duration, and filters —for example, only previously failed questions. The resulting exam is timed and saved in the history like any other mock exam.

Sabero's mock exams include a real timer that replicates ICFES Saber 11 pacing. The suggested time per question is shown during the exam and progress is saved automatically in case of accidental window closure.

Sabero allows unlimited mock exams with an active subscription. There is no limit on attempts per exam or per day.

Sabero's flashcards are generated from any question in the bank or after an exam and use a spaced repetition system: cards the student struggles to remember show up more often, optimizing study for long-term retention.

Sabero allows creating flashcards manually in addition to the AI-generated ones. They are accessed from the view of any question and manual flashcards integrate with the same spaced repetition system.

Sabero's IRT score is an estimate of the student's ability level computed with Item Response Theory (IRT), the same statistical methodology the official ICFES uses to compute the Saber 11 score. It updates after each completed exam.

Sabero's IRT score is an estimate based on the same ICFES methodology, but it is not the official score. It works as a comparative indicator of the student's level. The real score depends on the calibration of the official ICFES questions, which is confidential.

Sabero estimates the student's ability level with IRT after each exam. This estimate is indicative —it does not guarantee a specific score on the real ICFES—, but it shows improvement trends and the subjects that need more practice.

Sabero is available in Spanish (es-CO, default) and English (en). The language can be changed at any time from the profile or the selector in the top bar. The AI coach, AI tutor, and explanations respond in the configured language.

Sabero works as a Progressive Web App (PWA) on Android and iOS. It can be installed from the browser onto the device's home screen and works with an internet connection. It does not require a download from the App Store or Play Store.

Sabero requires an internet connection for mock exams, the AI tutor, the AI coach, and analytics. Some review features may be available offline, but the full experience requires a connection.

Sabero's monthly plan costs $— COP/month with a 0% launch discount that has no guaranteed expiration and can be withdrawn at any time. The first 0 days are completely free and require no credit card.

Sabero's monthly subscription can be canceled before the next renewal from the user profile, with no contracts or commitment. For quarterly and semi-annual plans, access is maintained until the end of the paid period.

Sabero's launch price can change without prior notice: the promotion has no guaranteed expiration date. Students with an active plan keep the contracted price until the end of that period, with no increases mid-subscription.

Sabero does not charge automatically when the free trial ends because no card is requested at sign-up. To continue, the student must enter a payment method and select a plan manually.

The ICFES Saber 11 evaluates five subjects according to the official ICFES orientation guide: Critical Reading, Mathematics, Social Studies and Citizenship, Natural Sciences, and English. Each subject has its own module and independent score, and Sabero covers all five with more than 10,000 questions in total.

The ICFES Saber 11 is Colombia's state examination taken by 11th grade students at the end of secondary education. Its results are the main admission criterion for most Colombian universities. It is administered by ICFES (Instituto Colombiano para la Evaluación de la Educación) and is offered twice a year.

The ICFES Saber 11 score is calculated with Item Response Theory (IRT), a statistical model that considers not only the number of correct answers but also the difficulty of each question. The global score is a weighted average of the five subjects, on a scale that approximately ranges from 0 to 500.

Sabero support is available from the support section inside the platform (requires an account). The team replies in Spanish and English, typically within 24 to 48 business hours.
