Vibe coding and AI agents classes in Pinner

Where can Pinner learners find the best vibe coding and AI agents classes?

Three Harrow wards carry most of what people call Pinner, and the ONS counted each separately at Census 2021: 13,137 usual residents in Pinner ward, 15,739 in Pinner South and 9,822 in Hatch End. Pinner Green, Pinnerwood Park and Rayners Lane are recorded suburban areas there too. Lessons in vibe coding, AI agents, Python and maths run on live video with tutors based in India, for anyone aged six to 67, one-to-one or with five to ten classmates at a matching level. Every project begins with a plan, and the Pinner project asks how detailed that plan needs to be. An agent that sketches a route along main roads first and fills in side streets afterwards did about a quarter of the searching and walked a typical 8% further. Your first lesson is free, with a course recommendation at the end; from then on a group seat is USD 100 per month and one-to-one is USD 150 per month.

Nobody plans a long journey one paving stone at a time. You decide on the big roads first and sort out the last few turnings when you get there. AI planners do the same thing under the name hierarchical planning, and coding agents do it when they write an outline before any code. It saves a great deal of effort, but it is a shortcut, and shortcuts have a price. Using OpenStreetMap's walking network for Pinner, this project counts both: how much searching the outline-first planner avoids, and how much longer its routes turn out to be.

Pinner and Harrow

Pinner, Pinner South, Hatch End and Rayners Lane

Ward counts from Census 2021 for the west of Harrow, and the places on record.

Census 2021 usual residents for three 2022 wards of Harrow, ONS via Nomis
WardResidents (2021)
Pinner South15,739
Pinner13,137
Hatch End9,822

Each row is one ward, and we have not added them up, because no published figure matches "Pinner" as residents use the name. Postcodes.io lists Hatch End, Pinner Green, Pinnerwood Park and Rayners Lane as suburban areas in HA5 and North Harrow as one in HA2, all within the borough of Harrow, with Pinner itself held as a settlement. Schools here teach the English national curriculum, so we talk in school years, keep GCSE and A level on the map, and pause over any holiday dates you give us.

Borough, city and method

For the whole borough see coding classes in Harrow; for the capital, London. Our case for planning before prompting is on learn to think, not just use AI tools.

The Pinner project

Hierarchical planning: main roads first, side streets later

Two planners, 500 walks, and a count of both effort and distance.

OpenStreetMap gives Pinner a walking network of 2,021 junctions and 143.3 km. Of that, 25.5 km is tagged as a primary, secondary or tertiary road, touching 463 junctions; this is the outline layer. We drew 500 random walks between side-street junctions and planned each one twice. The flat planner runs Dijkstra's algorithm across everything until it reaches the goal. The two-level planner finds the closest main-road junction to each end, plans between those two on the outline layer alone, and joins the three pieces together.

Flat against two-level route planning in Pinner, our Python run on OpenStreetMap data
MeasureFlatTwo-level
Junctions examined, all 500 walks495,141127,714
Junctions examined, typical walkabout 950about 255
Route length, typical walkshortest1.08 times shortest
Walks more than 1.5 times the shortestnone10.4%
Same, for walks under 800 mnone31.6%
Same, for walks of 2 km or morenone3.4%

The two-level planner looked at roughly a quarter as many junctions, and its typical route was about 8% longer than the true shortest; 41.6% of its routes were within 5%. The cost is not spread evenly. On long walks the detour to a main road barely matters, and only 3.4% of walks of 2 km or more came out over one and a half times the shortest. On short walks the outline is a liability: two addresses a few side streets apart get sent out to a main road and back, and the worst of our 57 short walks was nearly 15 times longer than it needed to be. The lesson learners take away is a rule about scale: use the outline for big jobs, and notice when a job is small enough to solve directly.

Ages 8 to 11

Plan a walk across a paper map using only the thick roads, then try a short hop and see the plan go wrong.

Ages 11 to 15

Build a small street graph in Python and mark which streets belong to the outline.

Ages 15 and up

Write both planners, count junctions examined, and find the distance at which the outline starts to pay.

Whose data, whose sums

Street and path geometry, and the road class tags, come from OpenStreetMap contributors under the Open Database Licence through the Overpass API. The planners, the 500 walks and the comparisons are ours.

Planning and AI

What this teaches about vibe coding and AI agents

An outline is what makes a large task possible, and also where it can go astray.

From the Pinner planner to AI agents
In the planning projectWhen an agent plans
Outline first cut the search to a quarterSubgoals keep a large task manageable
Routes ran about 8% longerA fixed outline rules out some better answers
Short walks suffered mostSmall tasks do not need a grand plan
Each piece was solved on its ownEach step can be checked on its own
The main roads were chosen by someone elseA plan is only as good as its outline

Vibe coding means describing a program to an AI in ordinary language and steering what it writes. Asked for a whole app in one prompt, an AI tends to lose track; asked for an outline, then one part at a time, it does far better, and the learner can test every part. That is hierarchical planning done by a person. AI agents do it for themselves, breaking a goal into subgoals and working through them, which is why a poor outline can send a capable agent the long way round. Pinner learners write the outline before the prompt and ask whether the job even needs one. Building agents waits until Python is comfortable, generally from about sixteen upwards, and Copilot Studio agent lessons are one-to-one only. Read on at AI agents for students in the UK or understand the code, don't copy-paste.

This page is independent of OpenStreetMap, the ONS, Nomis and postcodes.io. We drew on what they publish openly; the planners and any error in the counts belong to Modern Age Coders.

AI and planning

What is hierarchical planning, and when does it go wrong?

Hierarchical planning solves a problem in outline first and fills in the detail afterwards; it goes wrong when the outline forces a detour, which happens most on small problems that never needed an outline.

Across 500 walks in Pinner, planning along main roads first examined 127,714 junctions where a flat search examined 495,141, with routes typically 8% longer; but 31.6% of walks under 800 m came out more than one and a half times the shortest.

A learner who has counted both sides asks of any plan, their own or an AI's: is this outline helping, or is it just in the way?

Pinner teenagers who can write an outline, and also say when to skip it, get much more out of an AI coding tool than those who only type prompts. The longer argument is in why teenagers should still learn to code in 2026.

Practicalities

Hatch End to Rayners Lane, by video

A laptop or desktop with a webcam and an ordinary home connection is enough.

Plan, then type

Learners write a short outline first and then the code themselves, sharing their screen so the tutor can question each step.

Level found in the trial

We see what the learner can already do and note any exam board.

Nothing to pay at first

The trial lesson is complete and free, and ends with a named course.

Small, matched classes

Five to ten people at one stage, joining from all over Britain.

Twice weekly

Paused in the school holidays when you ask.

Fixed UK time

Clock changes are absorbed at the tutors' end.

Why not a local room

A class only works when everyone in it is at the same stage, and one suburb seldom has enough learners at each stage. The whole country does.

Fees

Fees for Pinner

Pinner sits on our international rate card, the same one used for every learner outside India.

FAQ

Pinner questions

Planning, subgoals, vibe coding, agents and how lessons run.

How many people live in Pinner?

There is no single official figure. Census 2021 counted 13,137 usual residents in Pinner ward and 15,739 in Pinner South, published as separate wards of Harrow.

Can I take vibe coding and AI agents classes online from Pinner?

Yes. Everything is taught on live video, for ages 6 to 67, to Pinner, Hatch End, Rayners Lane and the rest of Harrow.

What is a subgoal?

A smaller target on the way to a bigger one. Reaching the main road is a subgoal of walking across Pinner; writing the login screen is a subgoal of building an app.

What is Dijkstra's algorithm?

A method for finding the shortest route through a network by always extending the closest unfinished point. It is exact, and its work grows with the size of the area searched.

What happens in the Pinner project?

Learners plan 500 walks twice, once over every street and once along main roads first, and compare the searching done with the distance walked.

How is vibe coding taught?

Outline first, then one part at a time with the AI, testing as you go. Children, teenagers and adults all do it.

When can a learner start on AI agents?

Once Python feels comfortable, usually from about sixteen; Copilot Studio agents are taught one-to-one.

Does this help with GCSE or A level?

It supports computer science and maths at both levels. We teach for understanding and do not promise grades.

What is the price?

The first lesson is free. After that, USD 100 each month for a group place, USD 150 each month for one-to-one.

Are school holidays respected?

Yes, give us the dates and lessons pause.
