Skip to contentCourses for Caerphilly ## Starting points for Caerphilly learners Think of a seven-year-old in Risca who counts everything, a Blackwood Year 6 eager to type code, an Ystrad Mynach teenager beginning WJEC GCSE Computer Science, and a Caerphilly adult who checks spreadsheets for a living. Each of them would open with a free lesson.

Figures for individual towns are the matching ONS built-up areas. | Town | Residents | Town | Residents | | --- | --- | --- | --- | | Caerphilly | 33,105 | Bargod | 8,035 | | Risca | 15,195 | Newbridge | 7,585 | | Blackwood | 12,620 | Bedwas | 6,460 | | Ystrad Mynach | 11,855 | Oakdale | 6,130 | | Pontllanfraith | 9,360 | Abertridwr and Senghenydd | 5,640 | Beyond the table come Abercarn, Rhymney, Aberbargoed, Llanbradach and New Tredegar, among others; our own output-area sums agree with every published figure to within five people. Pupils here follow the Curriculum for Wales before WJEC exam courses take over at GCSE and A level. Caerphilly County Borough Council sets the school holidays; we have not read them and plan breaks from each family's own dates. ### Cardiff and WJEC exams The capital has its own page at [Cardiff](/best-coding-class-in-cardiff). For exam help, see [WJEC GCSE Computer Science](/wjec-gcse-computer-science-help-wales) and [WJEC GCSE Digital Technology](/wjec-gcse-digital-technology-help-wales). The Caerphilly project ## A program that checks the brackets Find every pair of figures, convert, compare, flag. The learner saves the text of Cadw's record and writes a regular expression, a compact search pattern, that picks out every place where a number with an imperial unit is followed by a metric figure in brackets: inches with metres, feet with metres, tons with tonnes. For each pair, the program converts the imperial figure itself, one inch being 0.0254 metres and one foot 0.3048, and compares the result with the bracketed number. Anything more than 3 per cent apart is flagged for a human to look at. The program finds six pairs. | Pair in the record | Our conversion | Difference | Verdict | | --- | --- | --- | --- | | 42" (1.4m) | 1.067 m | +31.2 per cent | Flagged | | 6' (1.82m) | 1.829 m | -0.5 per cent | Agrees | | 24' (7.3m) | 7.315 m | -0.2 per cent | Agrees | | 28" (711mm) | 0.711 m | 0.0 per cent | Agrees | | 6000 tons (6120 tonnes) | 6,096 long tons or 5,443 short tons | Factor 1.020 | Definition question | | 3000 tons (3060 tonnes) | 3,048 long tons or 2,722 short tons | Factor 1.020 | Definition question | Four pairs agree to well within rounding. The cylinder figure does not: 42 inches works out at 1.067 metres, while the bracket says 1.4, almost a third more. The program cannot say which half is the slip, only that the two cannot both be right, which is exactly what a good checker should report. The tons are subtler. Britain's traditional long ton is about 1.016 tonnes and the American short ton about 0.907; the record's conversions multiply by 1.020, close to the long ton but not exact. Nothing is necessarily wrong here: rounded figures such as c 6,000 were converted roughly. But it shows why a program handling tons must ask which ton is meant. The learner then makes the checker sturdier: it must cope with commas in numbers, with mm as well as m, and with a pair written the other way round. Each new rule gets a small test of its own, so that fixing one case never quietly breaks another. ### Ages 8 to 11 Measure things in inches and centimetres, write both down, and build a Scratch quiz that spots a wrong pair. ### Ages 11 to 15 Write a Python function that converts inches and feet to metres and checks a list of pairs by hand-entered values. ### Ages 15 and up Use regular expressions to extract pairs from real text, set a tolerance, add tests, and handle the long ton and short ton. ### Checking, not blaming The figures are quoted as they appear in Cadw's record, which itself quotes an earlier description. Our program only reports that one pair is inconsistent; we do not claim which number is the mistake, or say anything about the engine beyond the record. Why the Elliot Colliery ## A winding engine from 1891 What Cadw's record describes. | Record detail | What it says | | --- | --- | | Pits | East and West Elliot pits, developed during the 1880s | | Engine | By Thornewill and Warham of Burton on Trent, installed 1891 | | Water | Used to lift about 6,000 tons of water a day soon after coal production began | | Upgrade | High pressure boilers and two extra cylinders added in 1904, about 2,000 horsepower | | Drum | A lighter semi-spiral drum known as a diabolo, with a reverse taper | | Later life | The pit closed in 1967; the building became a museum in the mid 1990s | Automatic consistency checks run through modern software everywhere: spreadsheets that flag totals, engineering tools that insist on units, and data pipelines that refuse figures that cannot both be true. Mixed units have caused expensive failures in engineering, which is why many teams now make the computer check every conversion. A Caerphilly pupil who has built one has a genuinely professional habit. We have no connection with Cadw or Caerphilly County Borough Council. The record's text belongs to Cadw; the checker, its conversions and any errors belong to us. Learning path ## From rulers to regular expressions Year bands are a starting guess; the trial lesson confirms it. Years 1 to 4 ### Measuring games Block coding with lengths, weights and simple comparisons. [Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Years 5 to 8 ### Units in code Typed Python converting units and checking answers. [Maths Through Coding](/courses/maths-through-coding)[Python and AI for Kids](/courses/python-ai-kids-masterclass)Years 9 to 13 ### Text and tests String processing, patterns and testing alongside WJEC GCSE and A level courses. [Python for Teens](/courses/python-complete-masterclass-teens)[Problem Solving for Teens](/courses/problem-solving-dsa-masterclass-teens)Adults ### Checking data Python and data analysis for adults who validate figures at work. [Data Analysis Course](/courses/data-analysis-mastery-course-college)[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)AI and conversions ## An AI can convert units in seconds. Will it notice a pair that does not match? Reading past an inconsistency is easier than flagging it. Give a chatbot a paragraph full of paired figures and ask for a summary, and it will usually repeat them faithfully, including a pair that cannot be right. Unless asked to check, it rarely stops to recompute, and it may not ask which ton was meant. A Caerphilly learner who has written a checker knows to make the computer verify, not just repeat. That discipline is exactly what AI-generated summaries of technical material need. Teenagers in Caerphilly should still learn to code in 2026 so they can make the machine check numbers instead of just repeating them. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How lessons work ## From Rhymney to Risca, lessons at home Towns throughout the county borough join by video in the same way. ### Learners write the code Each program is typed by the pupil while the teacher watches the shared screen and nudges when needed. ### Matched to Welsh schooling Whether it is Year 5 in Oakdale or Year 12 in Bargod, we look at the year and the Curriculum for Wales, and exam work follows the WJEC specifications. Lessons are in English. ### Free trial lesson A full lesson without charge, then an honest recommendation. ### Small classes at one level Five to ten learners at the same level, from many places. ### Term-time timetable Two lessons a week in term, with holidays off. ### Stays at UK time Clock changes do not move your lesson; our teachers on India time adjust instead. Why groups span several towns Five learners at one level, all free at the same hour, rarely live in one town. Grouping by level gives a pupil in Bedwas or Abercarn a class that fits.

FAQ ## Caerphilly questions The county borough, the colliery project and practical points. ### How many people live in Caerphilly county borough? The 2021 census counted 175,952 usual residents. ### What are the largest towns in Caerphilly county borough? ONS 2021 built-up areas: Caerphilly 33,105, Risca 15,195, Blackwood 12,620 and Ystrad Mynach 11,855. ### What is the Elliot Colliery project? Learners write a Python checker that finds every imperial and metric pair in Cadw's record, converts each one, and flags a cylinder size where 42 inches is bracketed as 1.4 m, though 42 inches is 1.07 m. ### What is the difference between a ton and a tonne? A tonne is 1,000 kilograms. The British long ton is about 1,016 kg and the American short ton about 907 kg, so tons must always be defined. ### When was the Elliot Colliery winding engine installed? In 1891, according to Cadw, which lists the engine house and engine at Grade II*. ### Are lessons held in Caerphilly? No building is involved: a learner in Rhymney and one in Risca each log in from home. ### Is WJEC GCSE Computer Science covered? It is, as is GCSE maths in Wales. Grades depend on the learner, so we promise understanding, not results. ### What ages can learn? We teach every age between six and 67. Younger children build with blocks, teenagers move on to Python and exam preparation, and adults usually want Python with real data. ### What does it cost? Lesson one costs nothing. From then on it is USD 100 per month for a group place or USD 150 per month for individual tuition. ### Do lessons stop in the school holidays? Yes. Send us your school's holiday weeks and we leave them free.
