02the method
AI tutor
An explanation for every question
No more getting stuck halfway through an exam. The tutor explains the concept, shows the procedure and asks you the questions that lead to the answer, without handing it over.

Math · limits
Evaluate the limit of (x² − 9) / (x − 3) as x → 3
I don't understand how to evaluate this limit
Substituting directly leaves you 0/0, which is not a result: it is a signal. Look at the numerator, x² − 9 is a difference of squares. Which two factors can you split it into?
I won't hand you the 6 — get thereIRT analytics

- Estimated ICFES-style score after every exam
- Performance by subject and by specific topic
- Week-by-week progress: see how much your IRT score rose

Real student results
Feedback from students who tried the Sabero pilot in 2025
380→436+56 points
The AI tutor was really good for math. I'd ask about an integral and it would explain the whole procedure without giving me the answer directly. I had to get there on my own. I went up like 41 points in that area, which was my worst.
452
I thought my problem was math but the analytics showed the issue was Critical Reading. In three weeks I went from 54% to 81% accuracy just working on that. I really didn't expect it.
345→420+75 points
The mock exams are very similar to the real exam in format and timing. When I got to the ICFES I was already used to that pace and didn't get nervous like in other exams. That helps more than you'd think.

Frequently asked questions
Sabero is a Colombian ICFES Saber 11 exam preparation platform with 3,000+ official-format questions, with hundreds of new ones added each month, 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 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 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.
The AI tutor activates inside the exam and explains each question step by step, without revealing the direct answer. It guides the student through questions, develops the reasoning, and accepts unlimited follow-up questions. It responds in Spanish or English depending on the configured language.
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.
The 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 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.
