Postcodes.io places Finchley and Church End in N3, East Finchley in N2, and North Finchley and Woodside Park in N12, all within the London Borough of Barnet. Barnet schools follow England's national curriculum, and with the term dates from you, no Finchley lesson falls in a holiday week. ### Barnet, London and thinking first For more, see [coding classes in Barnet](/coding-classes-in-barnet-london) and the [London page](/best-coding-class-in-london). Why we teach judgement before tools is on [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Finchley project ## Precision-recall against ROC: finding rare areas in Barnet Census data One model, one borough, and a target made rarer step by step. From the Nomis API the learner collects four Census 2021 tables for all 1,113 output areas in Barnet. An area is labelled car-light if its share of households without a car is among the highest in the borough. The detector is a logistic regression fed three clues per area: how densely people live, how many households are a single person, and how much of the housing is flats. Its verdict on each area is always given without having trained on that area. The experiment is run four times, with car-light meaning the top half of areas, the top quarter, the top tenth and finally the top twentieth: just 56 areas where at least 56.4% of households have no car. | Car-light means | Positive areas | ROC AUC | Average precision | | --- | --- | --- | --- | | Top 50% of areas | 557 | 0.907 | 0.901 | | Top 25% | 279 | 0.908 | 0.750 | | Top 10% | 112 | 0.915 | 0.521 | | Top 5% | 56 | 0.905 | 0.359 | The ROC AUC hardly moves: about 0.91 in every row. Judged by that number alone, the model is equally good at all four tasks. Average precision, the summary of the precision-recall curve, tells a different story, sliding from 0.901 to 0.359. In practical terms, at the rarest setting the model must flag 209 areas to catch 45 of the 56 car-light ones, so 164 of its alarms are false and only about one in five is right. Even its 56 most confident picks are correct just 37.5% of the time. Nothing about the model changed between rows. What changed is how many negatives there are to be wrong about, which ROC ignores and precision counts. ### Ages 8 to 11 Hunt for five red counters hidden among a hundred blue ones, and tally the wrong grabs as well as the right ones. ### Ages 11 to 15 Train a simple classifier on Barnet areas in Python and count its hits and false alarms at one threshold. ### Ages 15 and up Plot ROC and precision-recall curves side by side as the target gets rarer and explain why they part. ### Census data, our classifier Counts are Office for National Statistics Census 2021 data from Nomis, under the Open Government Licence. The car-light label is our own teaching device, not an official category, and the model and every score are our work. Metrics and AI ## What this teaches about vibe coding and AI agents Good at ranking, poor at alarms: both can be true of the same detector. | In the Barnet project | When an AI system reports a score | | --- | --- | | ROC AUC stayed near 0.91 | Some scores are blind to rarity | | Average precision fell to 0.359 | Pick the metric that matches the job | | 164 false alarms for 45 finds | Translate scores into counts of mistakes | | The model never changed | The data mix can change the verdict | | Car-light was our own label | Know who defined the target, and how | An AI assistant asked to evaluate a detector will often print the ROC AUC, because most examples it learned from do. In a Finchley vibe coding lesson the learner describes the detector in words and an AI writes the Python; the learner then asks for the precision-recall curve and the raw count of false alarms before believing the headline. AI agents that screen messages, transactions or applications work on rare events all day, so this is the check that matters for them. Learners move on to building agents once they can write Python unaided, mostly from sixteen, and Copilot Studio agents are one-to-one lessons only. The idea underneath is on [understand the code, don't copy-paste](/understand-the-code-dont-copy-paste-uk); the agents pathway itself is on [our page for UK students](/ai-agents-course-for-students-uk). We have no tie to the Office for National Statistics, Nomis or postcodes.io beyond using their open data. The classifier and any mistakes in it are our own. Stages ## From counter hunts to honest metrics A Finchley learner's school year suggests a level; the trial lesson confirms it. Years 2 to 7 ### How to think Searching, sorting and counting the misses as carefully as the hits.

[Generative AI Course](/courses/complete-generative-ai-masterclass-college)[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)AI and metrics ## What is a precision-recall curve, and when is it better than ROC AUC? A precision-recall curve shows, for every threshold, what share of the positives a model finds and what share of its alarms are right; it is the better guide whenever positives are rare, because ROC AUC ignores how many false alarms that rarity creates. On 1,113 Barnet Census areas, one model kept a ROC AUC near 0.91 while its average precision fell from 0.901 to 0.359 as the target shrank from half the areas to one in twenty. After this project, a learner meeting any AI accuracy claim asks: how rare is the thing being detected, and out of every hundred alarms, how many are real? A Finchley teenager who can turn a score into a count of false alarms will not be dazzled by a 0.9, and that habit is learned by coding the test. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## East Finchley to Woodside Park, on video A Finchley learner needs a computer with a camera and broadband that carries a video call. ### The learner does the coding Each line and each run is theirs. Watching the shared screen, the tutor asks what the number on it actually measures. ### Level found at the trial A free first session shows us where to start, and any exam board goes on the record. ### Free Finchley trial No payment for lesson one; it closes with a course suggestion. ### Classes matched by level Groups of five to ten, with classmates from anywhere in the UK. ### Two sessions a week School holidays are left free. ### Unchanging time Our tutors absorb the British clock changes. Why the lessons are online Finding five Finchley learners at the same level with the same evening free would take months. On video, the class forms from the whole country. Fees ## Finchley fees Families in Finchley pay the international rate, the same one used in every country except India. First class**USD 0** A whole lesson free, then our recommendation. Group tuition**USD 100** Roughly eight live small-group lessons per month. Private tuition**USD 150** Roughly eight live private lessons per month. Finchley fees are set in US dollars and there is no sterling price; an invoice is sent only after the trial has fixed the course and the weekly slot. The pricing page covers holidays, absences and switching format.

FAQ ## Finchley questions Rare targets, the Barnet Census project, vibe coding, Python and how Finchley lessons are arranged. ### How many people live in the Finchley wards? At the 2021 census East Finchley ward had 16,639 residents, Finchley Church End 18,840 and West Finchley 19,430. The ONS publishes them separately. ### Are coding and AI classes available online in Finchley? Yes. Learners aged 6 to 67 in East Finchley, North Finchley, Church End or anywhere in Barnet join by live video. ### What is average precision? A single number summarising the precision-recall curve: roughly, the precision you get averaged over all the levels of recall. It drops sharply when positives are rare, which ROC AUC does not. ### What is the difference between precision and recall? Recall is the share of real positives the model finds. Precision is the share of its positive calls that are correct. In our Barnet test, finding 80% of the rarest areas meant a precision of about 0.215. ### What does the Finchley project involve? Training one classifier on 1,113 Barnet Census areas to find car-light areas, making the target rarer in four steps, and comparing ROC AUC with average precision. ### Is vibe coding included? At every age. The learner sets out what the program should do, an AI writes a draft, and the learner checks it. ### How soon can a Finchley learner build AI agents? When they write Python unaided, mostly from sixteen; Copilot Studio agents are taught one-to-one. ### Do you support GCSE and A level pupils? Yes, for computer science and maths. We teach understanding and promise no grade. ### What do Finchley lessons cost? Nothing for the trial. Then USD 100 per month in a class or USD 150 per month for one-to-one teaching. ### Are lessons held in school holidays? No; send us the dates and we pause.
