What are the best coding classes in Worcester?
Worcester had 103,872 usual residents at the 2021 census, packed at 3,121.4 people per square kilometre against 433.5 for England. Worcester Cathedral says its present building was begun by Saint Wulfstan in 1084, and that King John asked in his will to be buried there. Worcester learners aged six to sixty-seven can take live video lessons with our teachers in India, on their own or in a class of five to ten at a matching stage, at times planned around UK school and work. The first lesson is free; afterwards a group place costs USD 100 a month and private lessons USD 150.
A sat-nav finding a route across Worcester could check every junction in the city, ring by ring, until it reaches the destination. That is Dijkstra's algorithm, and it is guaranteed to find the shortest route. A* finds exactly the same route but adds a sense of direction: it favours junctions that are closer, as the crow flies, to where it is going. On Ordnance Survey's map of 6,953 road links around the city, our teenagers ran 120 journeys, one for every pair of 16 places. The routes matched every time. But for a typical trip on one side of the Severn, Dijkstra examined 1,415 junctions and A* just 235.

The City of Worcester district is small and built up, with 3,121.4 residents per square kilometre, far above England as a whole.
People aged 20 to 24 made up 7.2% of residents in 2021, against 6.0% nationally, and so did people aged 30 to 34.
Of the 98,593 residents aged five and over, 20,328 were studying, 20.6%, very close to the figure for England.
Our Worcester groups gather learners from every part of the city. A Year 4 child in Warndon might be making a first game, a Year 10 student in Barbourne starting GCSE Computer Science, and an adult in St John's learning Python for work, each placed in a small group at their own level.
From Worcester Cathedral's own heritage pages and Historic England's open listing data.
The cathedral says the first cathedral was founded in 680, Saint Oswald built a later one in 983, and Saint Wulfstan began the present building in 1084, when its crypt was started.
King John spent Christmas in Worcester in 1214 and asked in his will to be buried between the shrines of St Wulfstan and St Oswald. His original will is kept in the Cathedral Library.
Historic England lists the cathedral, Edgar Tower, the Guildhall, The Commandery, The Greyfriars and The Old Palace at Grade I, all first listed on 22 May 1954.
The cathedral also describes its 12th century Chapter House as thought to be the first round chapter house in the world. We have no connection with Worcester Cathedral, Worcester City Council, Historic England or Ordnance Survey. The city is on this page because it stands on both banks of the Severn, and a river crossed by very few roads is exactly the kind of obstacle that tests a route-finding algorithm.
Where the map comes from
Ordnance Survey Open Roads is a free map of every road in Great Britain as a network of links and junctions, with each link's length. OS Open Rivers supplies the line of the Severn, and OS Open Names the positions of the city's suburbs.
Dijkstra's algorithm spreads out evenly from the start, like ripples. A* adds a heuristic, a guess of the distance still to go, and explores the most promising junctions first. If the guess never overestimates, A* still finds the true shortest route.
| Journeys | Dijkstra | A* | Work saved by A* |
|---|---|---|---|
| Same side of the Severn (81) | 1,415 | 235 | 82% |
| Across the Severn (39) | 2,249 | 422 | 81% |
Take the 6,953 road links in a 12.5 kilometre square around the city: 6,148 junctions joined by 786.9 kilometres of road, each link labelled with its length.
For A*, the guess is the straight-line distance to the destination. No road can be shorter than a straight line, so the guess never overestimates, and the route found is always the shortest.
Run both algorithms on every pair of places and count the junctions each one examines. The routes matched on all 120 journeys; only the effort differed.
Inside our square only two roads cross the Severn, the A44 and the A4440, so the straight line across the water is often a poor guide. We expected A* to lose much of its advantage on cross-river trips. It did not: it saved 81% of the work across the river against 82% on the same side. Cross-river journeys were simply longer, so both methods did more work. Testing a hunch and reporting that it was wrong is as valuable as confirming one.
The examples show the range. From St John's to the city centre, the road route is 1,118 metres against 1,025 in a straight line, and A* examined 26 junctions where Dijkstra examined 307. From Warndon to Dines Green, 7,160 metres by road, A* examined 1,382 junctions against 4,370. The biggest gap between road and crow is between Ronkswood and Tolladine: 1,529 metres by road for places 485 metres apart.
Practised on Worcester's roads, then used in sat-navs, games, delivery planning, robots and puzzle solvers.
| Question | For Worcester | What goes wrong if you skip it |
|---|---|---|
| What is the network? | OS Open Roads links and junctions in a set square | Routes that leave the map or miss a road |
| What does a link cost? | Its length in metres | Shortest in distance confused with quickest in time |
| Is the guess admissible? | Straight-line distance never overestimates | A faster search that returns a longer route |
| How is it checked? | Every A* route compared with Dijkstra | An optimisation that quietly changed the answer |
| What was measured? | Junctions examined, on identical routes | Speed claims with nothing to compare against |
The second row matters most for real journeys. We measured distance, not time, because Open Roads gives lengths but not traffic. A route that is shortest in metres can be slow at rush hour. A* works just as well with travel time as the cost, as long as the guess still never overestimates.

Python Automation CourseData Science CourseBecause A* is one of the founding ideas of artificial intelligence, and building it shows what a good guess is worth.
A* was developed as part of early AI research into planning, and the idea of search guided by an estimate still runs through game engines, robot planners and the systems that decide what an AI model tries next. A learner who has watched a simple straight-line guess cut the work by around 80% understands why good estimates matter so much.
The Worcester project also shows how to check a clever method. Every A* route was compared with Dijkstra's, and they matched 120 times out of 120. That habit, proving a faster method still gives the right answer, is exactly what AI engineers need when they speed up a system.
So a Worcester teenager should keep learning to code in 2026, in a city split by a river with few crossings: computers can search a map in milliseconds, but someone has to choose the guess and check it never misleads. The longer argument is in why coding is worth learning in 2026.
Worcester straddles the Severn, with only a handful of road crossings. Online, both banks are the same distance from the lesson.
A learner in Lower Wick and another in Blackpole can share a lesson without either of them crossing the river.
We follow the English curriculum from Reception through each Key Stage to GCSE and A level, with every lesson taught in English.
The free session works on a genuine task and ends with our advice on level, course and a weekly slot. No card is needed.
Five to ten learners at the same stage, from Worcester, across the UK and abroad, so every level has workable times.
Two fixed lessons each week, around eight a month, with half terms and exams planned with the teacher in advance.
A 5.30 pm lesson in Worcester is 10 pm for our teachers in summer and 11 pm in winter, as India does not change its clocks; they plan their evenings around UK learners.
Across Worcestershire
Families in Droitwich, Malvern, Pershore or Evesham join the very same classes, since every group is online and formed by level.
A free first lesson, then one monthly fee.
A whole lesson free of charge, ending with advice on level, course and a weekly time.
About eight live lessons a month in a group of five to ten learners at one stage.

The first task is matched to the learner: a paper maze game for a young child, a short Python program that finds a route on a tiny map for a beginner, or Ordnance Survey roads and A* search for a teenager ready for real data.
What Worcester families ask us most.
Census 2021 counted 103,872 usual residents in the City of Worcester district, with 102,059 in households and 1,813 in communal establishments.
It is very compact, at 3,121.4 residents per square kilometre against 433.5, and has slightly more young adults: 7.2% were aged 20 to 24 in 2021, against 6.0%. Its student share, 20.6%, is close to England's.
A route-finding algorithm that explores the most promising junctions first, using a guess of the remaining distance. If the guess never overestimates, as a straight line never does on roads, A* is guaranteed to find the shortest route.
Across 120 journeys between suburbs, A* found the same routes as Dijkstra's algorithm while examining far fewer junctions: a median of 235 against 1,415 on one side of the Severn, and 422 against 2,249 across it.
From Ordnance Survey's free Open Roads, Open Rivers and Open Names datasets, which give the road network, the line of the Severn and the positions of the suburbs.
Worcester Cathedral says King John spent Christmas in Worcester in 1214, asked in his will to be buried in the cathedral, and lies in front of its High Altar; his original will is in the Cathedral Library. We are not connected with the cathedral.
On weekday afternoons or evenings, or at weekends, at a UK time we settle in the free lesson. India is four and a half hours ahead of Worcester in summer and five and a half in winter.
No. We have no Worcester centre and no premises anywhere in the UK, because all teaching is live online. A learner needs a computer with sound and a steady connection, and our phone number is Indian.
The first lesson is free. Then a group place is USD 100 a month for two live lessons a week, about eight a month, with five to ten learners; one-to-one lessons on the same timetable are USD 150 a month. Course, format and time are agreed before any charge.
By level, pace and goals rather than age or address, with five to ten learners at one stage. If no group suits the learner's week, we offer one-to-one lessons instead.
Down the Severn, the Gloucester page matches two river curves that do not keep time, and Coventry chains its bus stops into groups. Durham traces lines of sight across a grid of heights. The England guide sets out school stages, and the UK coding page links every other city.
