The short answer Modern Age Coders gives live online coding classes in English to teenagers, children and adults in Santiago de Surco, Lima. Teenagers learn Python, then C++, problem solving and AI, the skills behind Peru's free school contests such as the OPI and OPEIA run by UTEC. Children start with Scratch at 6 and Python at about 9; adults learn Python and data. Each lesson is led in real time over video by a mentor working from India; students join a batch of fifteen to twenty or learn one to one, and the family sets the hour on Peru time. Where Surco learners start ## Three courses, two of them for secundaria Python from zero for teenagers, problem solving for those who already code and want contest-style thinking, and Scratch for younger brothers and sisters. [![Python for Teens course thumbnail](/images/python-teens.webp) CSU / 01 Python for Teens For 13 to 18 year olds who have never coded. Real typed programs from the first lesson, then files, data and larger projects. Python is also one of the two languages the OPI accepted in its first round under the 2025 rules.

INEI's census of 2025 counted 28,204 people aged 12 to 17 in Santiago de Surco, out of a total population of 402,074, nearly 4% of everyone in Lima Metropolitana by our own division. ### What INEI counted Of the 386,432 people INEI actually counted in Surco (it estimates 15,642 more were missed), 24,155 were aged 6 to 11 and 28,204 were aged 12 to 17. The district's adults are a large majority, as everywhere in Lima, with 86,108 people of 60 and over and 85,158 aged 30 to 44. By our arithmetic, teenagers of 12 to 17 are about 7.3% of the people counted in Surco, a little below the 9.0% share across Lima Metropolitana. The share is modest; the number is not, because Surco is so large. ### Why it shapes this page Twenty-eight thousand teenagers means twenty-eight thousand different timetables, interests and levels. A live online class does not need a crowd of beginners at the same level in one building; it puts a Surco teenager into a group of the right age and level drawn from many places. Surco borders Miraflores, Surquillo, San Borja, Ate, La Molina, San Juan de Miraflores, Chorrillos and Barranco. Teenagers in any of those districts join the same classes, at the same hours. Source: INEI, Censos Nacionales 2025, demographic indicators for Lima Metropolitana, Cuadro N.° 1 and Cuadro N.° 3, saved on 8 November 2026; INEI lists the district as Santiago de Surco. The shares are our own calculations on the counted population; we never add INEI's age groups into new totals. Teenagers in Peru are almost all online already: INEI's household survey for the second quarter of 2026 found that 92.5% of 12 to 18 year olds in the country used the internet. What most of them have not met is programming, because the national curriculum has no computing subject in secundaria. That gap, not access, is what our classes fill. Contests in 2026 ## Which computing and maths contests can a Surco teenager enter, and when? Four national contests matter most for a secondary pupil interested in programming or maths. Three are organised by UTEC and are free for every secundaria student in Peru; the fourth, the ONEM, is MINEDU's maths olympiad, entered through the school. | Contest | Organiser | What it tests | 2026 dates | | --- | --- | --- | --- | | OPI, Olimpiada Peruana de Informática | UTEC | Algorithmic programming | Entries closed 18 March; final (Fase 2) 11 April | | OPEIA, Olimpiada Peruana de Inteligencia Artificial | UTEC | Artificial intelligence | Entries closed 18 March; held 19 March, one sitting | | OPECIA, Olimpiada Peruana de Ciberseguridad | UTEC | Cybersecurity | Entries closed 26 April; held 27 April, one sitting | | ONEM, Olimpiada Nacional Escolar de Matemática (XXII edition) | MINEDU | Mathematical problem solving | School stage 8 July; national stage 11 October at Huampaní | Sources: UTEC, Olimpiadas Peruanas de Computación home page (opi.utec.edu.pe), read 8 November 2026; UGEL 06, Oficio Múltiple 164-2026 on the XXII ONEM; El Peruano, report of 11 October 2026 on the ONEM national stage. All dates are in 2026. We are not connected with UTEC, MINEDU or any organiser, and we do not reproduce their problems. ### The UTEC olympiads UTEC describes its Olimpiadas Peruanas de Computación as open free of charge to all secondary students in the country. The OPI selects the students who represent Peru at the Ibero-American and International Olympiads in Informatics; under the 2025 rules, the top four of the final went to the IOI. OPEIA's 2025 team represented Peru at the international AI olympiad, the IOAI. The 2025 OPI rules allowed students up to 20 years old on 1 July 2025 who were at school in Peru that year or had finished in 2024. They also banned generative AI for solving problems, which says plainly what the contest values: a student who can reason alone. ### The ONEM The ONEM has three levels: 1st and 2nd of secundaria, 3rd and 4th, and 5th. Pupils of public schools compete in the Alfa category and those of private schools in Beta. The 2026 school-stage paper had ten questions where the student writes the answer, with two hours to solve them. El Peruano reported that ONEM 2026 drew more than 1.7 million secondary pupils from its first stage, and that 237 reached the national stage on Sunday 11 October 2026. Entry is through the school, so a Surco pupil who wants to take part should ask there. For maths specifically, our page on [ONEM preparation in English](/onem-preparation-in-english) explains the levels, the stages and how a student who learns maths in English handles a paper written in Spanish. On this page the focus is programming. What contests reward ## What do the contests actually reward? Reasoning under pressure, without help. A contest problem gives a precise task, limits on time and memory, and test cases the student cannot see. A program that is nearly right scores little. ### Exactness A contest judge does not read the code generously. It runs it against hidden cases, including the awkward ones: an empty list, one item, the largest allowed input. Our students learn to write those cases themselves before submitting anything. ### Efficiency A correct program that takes too long fails. Teenagers learn to count roughly how many steps a solution needs, and why sorting first or remembering earlier results can turn a slow idea into a fast one. ### Explanation We ask every student to explain, in English, why their solution works. If they cannot, it usually does not. The habit carries straight into school exams, university and any job that involves code. None of this is copied from a contest. We do not reproduce any organiser's problems or solutions; every practice problem in our classes is written by us and labelled as ours. We teach the kind of thinking the contests reward, and leave the contests themselves to the students and their schools. For a broader view of teenage coding in Peru, see [coding classes for teens in Peru](/coding-classes-for-teens-peru). Python or C++ ## Should a Surco teenager learn Python or C++ first? Python first, for almost everyone, then C++ for those who want to go far in algorithmic contests. The OPI's own 2025 rules show why both matter. ### Why Python first Python reads close to plain English, so a beginner spends the first months on ideas rather than punctuation: variables, loops, lists, functions. Under the 2025 OPI rules, the first round accepted Python as well as C++, so a student who knows Python well can already take part. Python is also the language of data and AI, which matters for OPEIA and for most of what a teenager will build outside contests. ### When C++ comes in The same rules allowed only C++ in the in-person final. That reflects international practice in informatics olympiads, where C++ is fast and gives precise control over memory. We move a student to C++ once they think comfortably in Python. The ideas transfer; only the syntax and a few habits change. Our C++ for teens course takes them from there to the standard library and algorithms. A teenager who does not care about contests loses nothing by following the same path. Python, then a second language, is a solid route into any branch of computing, and Java or app development can take the place of C++ for those who would rather build than compete. A real lesson ## What does a lesson look like? Merging two calendars in Python We teach this to teenagers of about 13 upwards, using the contest dates above and the national school calendar for 2026. It looks like a small task and hides a classic mistake that turns up in professional code, in contest solutions and in exams. ### The task A student keeps two lists, each already in date order: the contest dates, and the main dates of MINEDU's 2026 school calendar (RM 501-2025-MINEDU), such as the start of the first teaching block and the weeks set aside for staff planning. The goal is one list for the whole year, still in order. Sorting everything again would work, but there is a faster idea: walk along both lists at once, always taking the earlier of the two front items. That is the merge step inside merge sort, and it is worth understanding properly. ### The bug Version 1 stops as soon as either list runs out. The contest list ends on 11 October, so the loop stops there, and two school dates, the staff planning week from 12 October and the end of teaching on 18 December, are simply dropped. Nothing crashes, and the list that comes out is in perfect order. Only counting the items gives the game away: 9 kept out of 11. This is the **forgotten tail**, and the fix is two lines. ***Version 1: a merge that stops too early**Python* ``` contests = [(3, 18, "OPI and OPEIA entries close"), (3, 19, "OPEIA, one sitting"), (4, 11, "OPI final"), (4, 27, "OPECIA, one sitting"), (7, 8, "ONEM school stage"), (10, 11, "ONEM national stage")] school = [(3, 16, "teaching block 1 begins"), (5, 18, "staff planning week"), (7, 27, "two staff planning weeks"), (10, 12, "staff planning week"), (12, 18, "teaching block 4 ends")] def merge(a, b): out = [] i = j = 0 while i < len(a) and j < len(b): if a[i] <= b[j]: out.append(a[i]) i += 1 else: out.append(b[j]) j += 1 return out year = merge(contests, school) print("Dates kept:", len(year), "of", len(contests) + len(school)) print("Last date:", year[-1]) ``` It prints `Dates kept: 9 of 11` and `Last date: (10, 11, 'ONEM national stage')`. ***Version 2: add what is left, then check against sorted()**Python* ``` # the same two lists as Version 1 def merge(a, b): out = [] i = j = 0 while i < len(a) and j < len(b): if a[i] <= b[j]: out.append(a[i]) i += 1 else: out.append(b[j]) j += 1 out.extend(a[i:]) out.extend(b[j:]) return out year = merge(contests, school) print("Dates kept:", len(year), "of", len(contests) + len(school)) print("Same as sorted():", year == sorted(contests + school)) for month, day, what in year: print(f"{day:02d}/{month:02d} {what}") ``` With the two lists from Version 1 above it, it prints `Dates kept: 11 of 11`, `Same as sorted(): True`, then the whole year from `16/03 teaching block 1 begins` to `18/12 teaching block 4 ends`, including `11/10 ONEM national stage` followed by `12/10 staff planning week`. After the loop, at most one of the two lists still has items, and those items are already in order and later than everything taken so far. `out.extend(a[i:])` and `out.extend(b[j:])` add whatever remains; one of them adds nothing. Comparing the result with `sorted(contests + school)` is a cheap way to test the merge on real data before trusting it on anything bigger. Two smaller lessons sit inside this one. Python compares the tuples field by field, month first and then day, which is why storing a date as (month, day) sorts correctly while "day/month" text would not. And the `<=` in the comparison means that if two items fall on the same date, the one from the first list comes first, a property called stability that matters when order carries meaning. 1. **Warm-up, no computer.** Two friends each hold a pile of numbered cards in order. Merge them into one pile using only the top card of each. When do you stop looking at one of the piles? 2. **First Python.** Type Version 1 and predict which dates go missing before you run it. Then swap the two lists in the call. Which dates disappear now? 3. **Going further.** Count how many comparisons the merge makes, and compare that with the number of items. Why can it never need more comparisons than items? 4. **Contest style.** Merge three sorted lists. Then write, in two English sentences, how you would merge ten of them without comparing every front item every time. Why online ## Why learn online from Surco rather than at an academy across Lima? Because a teenager's time is short. Between school, homework, sport and family, an evening lost to travel is an evening not spent programming. ### The journey that disappears We do not publish traffic estimates without a source. Surco families already know what a trip across the city at rush hour costs. A class at home costs nothing in travel, and a teenager can go straight from the end of a lesson back to homework. It also removes the parent from the timetable. A fifteen year old can log in alone, at an agreed hour, without anybody driving. ### Live, not recorded Online here means live. The mentor watches the student's screen, asks why a line is there, waits for the answer, and corrects the reasoning on the spot. A recorded course cannot notice that a student has misunderstood a loop. The same mentor stays with the student, so by the third month they know the student's habits, strengths and the mistakes worth watching for. Spanish-speaking parents planning January and February will find a summer plan in our guide to [vacaciones útiles de programación en Surco](/vacaciones-utiles-de-programacion-surco-lima), which plans a summer for brothers and sisters of different ages. For the school year itself, see in Spanish [clases de programación en Surco](/clases-de-programacion-surco). Every class described there is taught live in English, exactly as here. Surco times ## What time would a class be in Surco? Whenever the week allows. Peru stays five hours behind UTC in every month, India runs 630 minutes ahead of Peru, and so an hour agreed in March is the same hour in November. The rows below are conversions only. | Peru time, Surco | India time | Often chosen by | | --- | --- | --- | | 07:30 | 18:00 | A teenager before school | | 10:00 | 20:30 | A student in the summer break | | 14:30 | 01:00, next day | A pupil home early | | 17:30 | 04:00, next day | A teenager after school | | 20:00 | 06:30, next day | An adult in the evening | Clock rules from the IANA tz database: zone America/Lima, which has had no daylight saving since 1994, and zone Asia/Kolkata. Conversions are our arithmetic, and the same on every day of the calendar. Booking works in local time for both sides: you pick a Surco hour, and the mentor's calendar shows its India equivalent. Contest weeks, exams and holidays can move a class by agreement; the regular hour stays yours. Milestones ## How a Surco teenager moves from first program to contest-ready Our own stages, used to place a student and to tell parents plainly what has changed. They are not a contest standard and promise no result. | Stage | Typical point | The student can | In English, the student can | | --- | --- | --- | --- | | 1. Programs | Months 1 to 2 | Write Python with input, decisions and loops | Say what a program will print before running it | | 2. Collections | Months 3 to 4 | Use lists, dictionaries and functions | Describe a bug and where it hid | | 3. Algorithms | Months 5 to 7 | Merge, search and sort, and test the edges | Explain the forgotten tail in a merge | | 4. Efficiency | Months 8 to 10 | Estimate steps and choose a faster method | Justify a choice of data structure | | 5. Second language | Year 2 | Write the same solutions in C++ or Java | Compare the two languages fairly | | 6. Contest practice | Year 2 on | Solve timed problems of ours with hidden cases | Argue why a solution is correct | ### For parents Stage 3 is the merge lesson above. Students who reach it start testing their own work without being asked, which is the change worth paying for. Contest results depend on the student and the contest; we promise none. ### For students When a loop ends, ask what it left behind. If your program agrees with sorted() on real data, you have a test. If you never checked, you have a hope. More courses ## Nine more courses for Surco learners Taught live in English, each with a regular mentor and a choice of group or private lessons.

The teachers are incredibly knowledgeable and passionate about coding." Ritu Kedia Parent Surco families ask ## Coding classes in Surco: questions and answers ### Are the classes in Spanish? No. Every class is live, online and taught in English only. Mentors keep their sentences short and their pace steady, and wait for answers, so a teenager whose spoken English is still developing can follow. Python and C++ are written in English keywords anyway, so the class and the code share one language. ### Can your classes get my child into the OPI final or an ONEM medal? No one can promise that, and we do not. We teach the reasoning these contests reward, with problems we write ourselves. Results depend on the student, the contest and the day. We are not connected with UTEC, MINEDU or any contest organiser. ### Does my teenager need to know how to code already? No. Python for Teens starts from nothing. Students who already code are placed at their level after the free first class, and may go straight to problem solving or C++. ### When are classes in Surco time? Any day, any time, flexible: choose a batch, or for a very personalised plan choose 1-on-1 at the hour that suits your family. With no clock changes in either country, 17:30 in Surco is 04:00 the next day in India. ### How does a student enter the ONEM? Through their school. The ONEM is MINEDU's maths olympiad, with a school stage first; in 2026 it was held on 8 July. Pupils of public schools compete in the Alfa category and private-school pupils in Beta. Ask the school about the 2027 edition. ### Are the UTEC olympiads free? UTEC says its Olimpiadas Peruanas de Computación, the OPI, OPEIA and OPECIA, are open free of charge to all secondary students in Peru. Check opi.utec.edu.pe for each year's dates and rules. ### Can my teenager use AI tools in class? Only age-appropriate ones, and only after reasoning through the problem alone. Claude is for adults of 18 and over and ChatGPT needs a parent's permission under 18. The 2025 OPI rules banned generative AI for solving problems, so contest practice with us is done without it. ### Do you have a centre in Surco? No. We have no premises anywhere in Lima. All teaching is live over video, with mentors based in India, which is how a student in Surco joins a group of the right level at a convenient hour. ### What about younger children and parents? Children start with Scratch from 6 or Python from about 9, in groups of their own age. Adults can take Python, data analysis or AI courses. Many Surco families have two or three learners at once. ### How are fees paid? Monthly, by card, in US dollars. If your card is in soles, your bank converts each charge, so the amount can vary slightly from month to month. The first class is free and needs no card.

The mentor notes how they reason and how easily they follow spoken English, then recommends a starting course, a group or private lessons, and a time that fits the school week. Rather read first? [How we teach](/how-we-teach) describes a lesson, and the [course list](/courses) has every syllabus.
