First lesson free. Skip to contentCourse picks for Barnet ## Four courses for Barnet learners Think of a Year 2 child in Mill Hill who lines up toy cars in queues, a Year 9 pupil in Finchley who asks why traffic stops for no reason, a Year 12 student in Edgware considering engineering or economics, and a commuter in Golders Green who would like to model their own journey. Each can begin with a free lesson.

Each records how many vehicles pass and how fast, every fifteen minutes. The data ## Where the traffic figures come from National Highways publishes readings from motorway sensors through a free service called WebTRIS. This is what one site in Barnet offers. | Road | Active sites | Inactive sites | | --- | --- | --- | | M1 | 13 | 45 | | A1 | 5 | 2 | | Other | 0 | 1 | We use site M1/2116B, on the southbound M1 and inside the borough boundary by our check, because its March 2025 record is nearly complete: 2,962 of 2,972 fifteen-minute slots carry a count and an average speed. Later months returned empty rows when we asked on 25 September 2026, so the page uses March 2025 and says so. For the learner, the data is a single download and a spreadsheet's worth of rows. We would normally list the borough's libraries here too. Barnet Council's website answered our automated reader with a bot-protection page, and we do not try to get round such checks, so this page gives no library list; the council's own site is the place to find one. Signature project ## Traffic jams from nowhere: four rules and a ring road Learners code a famous traffic model, the Nagel-Schreckenberg cellular automaton, and watch jams form on an empty road. ### 1. Boxes and cars A circular road of 2,000 boxes, each 7.5 metres long. Every car has a speed from 0 to 5 boxes a second; 5 is about 84 mph. ### 2. Four rules, every second Speed up by one if below the limit. Slow down so as not to hit the car ahead. With probability p, slow by one more for no reason. Then move. ### 3. Fill the road and measure Try more and more cars, and for each density measure the flow, the number of cars an hour passing any point, and how many are stopped. | Cars per mile | Perfect drivers: flow | Random braking p = 0.3: flow | Random braking: cars stopped | | --- | --- | --- | --- | | 6.4 | 540 | 507 | 0% | | 17.2 | 1,440 | 1,343 | 0% | | 21.5 | 1,800 | 1,648 | 0.4% | | 25.7 | 2,160 | 1,679 | 8.2% | | 32.2 | 2,700 | 1,627 | 19.0% | | 42.9 | 2,880 | 1,568 | 30.6% | | 64.4 | 2,520 | 1,416 | 43.7% | With perfect drivers the road behaves as you would hope: flow grows steadily until the cars are close together, and nobody stops until beyond 32 cars a mile. Allow each driver a small chance of braking for no reason, and the road reaches its most productive point at about 26 cars a mile. Beyond it, adding cars lowers the flow, and at that same density about one car in twelve is standing still at any moment, although nothing is blocking the road. A cluster of stopped cars with nothing ahead of it is exactly what a driver meets as a jam with no visible cause. ### Why an AI does not settle this for you An assistant will write this simulation in a moment. What it cannot do for a learner is the part that makes it science: choosing to compare perfect drivers with imperfect ones, noticing that the jam needs no obstacle, and then checking the model against real sensor data before believing it. A learner who has done all three knows that a model is a claim to be tested, not an answer, which is true of every simulation in engineering, economics and climate science. Checking against the M1 ## The same shape in real traffic: site M1/2116B, March 2025 Each fifteen-minute reading gives a flow and an average speed; flow divided by speed gives the density. Grouping the readings by density shows the real road's curve. | Vehicles per mile | Readings | Typical flow, vehicles an hour | Typical speed | | --- | --- | --- | --- | | 0 to 20 | 1,546 | 450 | 50 mph | | 20 to 40 | 1,103 | 1,348 | 51 mph | | 40 to 60 | 79 | 2,080 | 47 mph | | 60 to 80 | 28 | 2,574 | 38 mph | | 80 to 120 | 40 | 2,682 | 26 mph | | 120 and above | 166 | 2,414 | 10 mph | The real road climbs and then falls just as the model does: as it fills beyond about 80 to 120 vehicles a mile, flow drops back and speeds collapse to a crawl, and in March 2025 about one fifteen-minute slot in twelve averaged under 40 mph. The numbers are not the same as the model's, and should not be: the sensor counts every lane of the carriageway together, and real drivers, lorries and junctions are messier than four rules. What matches is the shape, a road that carries less once it is too full, and that is the lesson. National Highways, Barnet Council, Historic England, TfL and the ONS supplied the data here and have no tie to Modern Age Coders. The readings belong to National Highways; turning them into densities, building the model and working out each percentage was done by us on 25 September 2026, with the random seed written down so anyone can rerun it. Getting around ## From High Barnet to Golders Green, and no motorway needed Barnet has a motorway, a trunk road and the Northern line. An online lesson needs none of them. ### High Barnet TfL's open data lists the Northern line at High Barnet, in the north of the borough. ### North to south A learner in Mill Hill and one in Golders Green can share a group from their own homes, whatever the M1 is doing. ### No queue to join The traffic model shows how a road fills up. An online class never does: learners are placed in groups of five to ten by level. Barnet and the rest of London Barnet is one of London's 32 boroughs. The [London page](/best-coding-class-in-london) lists every borough and the City, and links each as its page is published, including [Brent](/coding-classes-in-brent-london) and [Harrow](/coding-classes-in-harrow-london) to the west. Learning ladder ## From one simple rule to a model tested on real data Where a learner starts depends on what they show us in the free lesson, not on the year group printed on their school report. Ages 6 to 10 ### Simple rules, big patterns Children give sprites one rule each and watch lines, crowds and queues appear on their own. [Scratch Coding for Kids](/courses/scratch-programming-complete-course)[Coding for Kids](/courses/kids-coding-blocks-masterclass)Ages 10 to 13 ### Lists that move Python where a list of cars moves step by step, and a count shows how many get through. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Ages 13 to 18 ### Simulate, then test Cellular automata, random numbers with a seed and real sensor data, the core of a strong computing or maths project. [Python for Teens](/courses/python-complete-masterclass-teens)[Full Stack Web Development for Teens](/courses/full-stack-web-development-teens-masterclass)Ages 18 to 67 ### Models as claims Adults learn to treat a forecast as a claim to test, and to compare it with data before acting on it. [Data and AI Analytics for Non-Programmers (Excel, Sheets, Power BI)](/courses/data-and-ai-analytics-for-non-programmers-course)[Python Automation Course](/courses/python-ai-automation-masterclass-college)Coding and AI ## An AI can write a traffic simulation in seconds. Why should a Barnet teenager learn to build and test one? Because a simulation that is never checked against the world is only a very detailed guess. Ask for a traffic model and an assistant will produce a tidy cellular automaton, perhaps with an animation. It will not decide for you which question to ask of it: what happens when drivers are imperfect, what the fundamental diagram looks like, whether real roads agree. In our run the model says that random braking alone cuts a lane's top flow by about two fifths and leaves cars standing still on an empty road; the M1 in Barnet shows the same rise and fall. Models of epidemics, markets and climate carry the same risk of looking finished before they have been tested. A learner who has built this model and held it up against National Highways' data learns three lasting habits: change one thing at a time, fix the random seed so a result can be repeated, and compare shapes before numbers. The software can generate code without limit. Knowing what to test, and how to judge the answer, is the work people still do. Every useful model starts as someone's simple idea and survives only if it meets the data. A Barnet child who learns to code can be the one who builds that idea and has the discipline to test it. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## From Edgware to Finchley, lessons without a commute In every part of the borough, the lesson is as near as the nearest desk. ### Learn from home Most learners join from home with a laptop or desktop, headphones and a steady connection. ### English school terms We use the stages English schools use, from Key Stage 1 to sixth form, with GCSE and A level named plainly. All teaching is in English. ### A real first lesson The free first lesson is genuine work with a teacher and ends with a recommendation of level and course, with no card needed. ### Level-matched groups Classmates are chosen for being at the same stage, five to ten of them, drawn from well beyond Barnet so that a sensible hour is always available. ### Two sessions a week A typical class runs two evenings a week and takes time off around half terms, holidays and exam season, by arrangement. ### UK times always Teachers work from India; every invitation and reminder gives the time as it is in Barnet. A big borough, one matched group Barnet is home to nearly 390,000 people, yet a strong coding group still needs five learners at the same level and hour, so ours reach well beyond it. Fees ## Fees for Barnet families The first lesson is free, then there is one monthly fee, the same across the borough. First class**USD 0** A full first lesson with a teacher at no charge, ending with a suggested level, course and time. Group tuition**USD 100** Around eight live lessons a month, in a group of five to ten at the same stage. Private tuition**USD 150** Around eight live lessons a month, one teacher and one learner. Families in Finchley, Hendon or anywhere in Barnet pay in US dollars, as do all families outside India; the site carries no pound prices. No money changes hands before the free lesson has happened and you have picked a course and a weekly time. How pauses, missed classes and a switch from group to private lessons work is written up on the pricing page.

The 2021 Census counted 389,344 usual residents in the London Borough of Barnet, according to Office for National Statistics table TS001. ### Where does the M1 traffic data come from? From National Highways' WebTRIS service, which publishes fifteen-minute vehicle counts and average speeds from roadside sensors. We used site M1/2116B, on the southbound M1 inside Barnet, for March 2025. ### What is the Nagel-Schreckenberg model? A cellular automaton for traffic: a road divided into boxes, where each car speeds up, keeps a safe gap, sometimes slows at random, and moves. From those four rules, jams appear with no obstacle on the road. ### Can traffic really jam with no cause? In the model, yes. With a small chance of random braking, about one car in twelve is stopped at 26 cars a mile per lane, although nothing blocks the road. The M1 data shows real traffic slowing sharply once the road is very full, the same shape. ### Why is the model's flow different from the M1's? The model is one lane of identical cars; the sensor counts every lane of the carriageway together, with lorries and junctions. The two share a shape, rising and then falling as the road fills, not exact numbers. ### When are lessons for Barnet learners? Once the free lesson is over we offer a weekly time from the classes at the learner's level that still have room. The teaching happens from India, yet every time in our messages is Barnet time. ### What does a learner need? A laptop or desktop, headphones or speakers, and a steady internet connection. For the traffic project, Python and one download of public data are enough. ### Is there a Modern Age Coders centre in Barnet? No. There is no Barnet centre and no premises anywhere in the UK, because every lesson is live online. A learner needs a computer with sound and a stable connection, and our phone number is Indian. ### What do coding classes in Barnet cost? The first lesson is free. After that, a group place costs USD 100 a month for two live lessons a week, about eight a month, with five to ten learners, and one-to-one teaching on the same timetable costs USD 150 a month. Nothing is charged until the course, format and time are agreed. ### How are the groups made up? By level, pace and goals rather than by age or neighbourhood, with five to ten learners at one stage. Where no group fits the learner's week, one-to-one lessons are offered.
