Carmarthenshire schools teach the Curriculum for Wales and enter older pupils for WJEC GCSE and A level courses. The county council fixes the school holidays; not having read its calendar, we plan each learner's breaks from the dates their family sends. ### Swansea and WJEC help The city of [Swansea](/best-coding-class-in-swansea) has its own page. For exams, see [GCSE Maths and Numeracy in Wales](/gcse-maths-and-numeracy-wales-help) and [WJEC GCSE Computer Science](/wjec-gcse-computer-science-help-wales). The Carmarthenshire project ## Measuring half an ellipse Rough formulas, Ramanujan, straight-line pieces and an exact method from Gauss. The span comes from the record: about 25 metres, so the half-span is 12.5. The rise is not given, so the learner tries invented values, mainly 7 metres. The arch is modelled as half an ellipse. The learner then measures its length five ways: two quick guesses, two formulas found by the Indian mathematician Srinivasa Ramanujan, a curve made of many short straight pieces, and an exact method based on Gauss's arithmetic-geometric mean, which repeatedly averages two numbers in two different ways until they agree. | Method | Length | Error | | --- | --- | --- | | Exact, arithmetic-geometric mean (5 steps) | 31.242807 m | Reference | | Pi times average of the two half-axes | 30.630528 m | 2.0 per cent short | | Straight line pieces, 16 of them | 31.192643 m | 5 cm short | | Straight line pieces, 1,024 of them | 31.242794 m | Under 0.02 mm short | | Ramanujan's first formula | 31.242775 m | About 0.03 mm short | | Ramanujan's second formula | 31.242807 m | A few billionths of a metre | The quick guesses are a couple of per cent out either way, which on a real arch would be about 60 centimetres. Chopping the curve into straight pieces works, but slowly: every time the number of pieces goes up four times, the error drops about sixteen times, so 1,024 pieces are needed for sub-millimetre accuracy. Ramanujan's formulas, published over a century ago, are astonishing; the second is right to a few billionths of a metre here. The arithmetic-geometric mean reaches the exact value in only five rounds of averaging, because its error roughly squares away at every step. Our own first version of the exact method had a bug and returned half the right length. It was caught by an easy test: when the rise equals the half-span, the arch is a semicircle, and every correct method must give pi times 12.5, 39.27 metres. Testing code against a case you already know the answer to is one of the most useful habits in programming. ### Ages 8 to 11 Lay string along drawn circles and ovals, measure it, and compare with a guess, then draw ovals in Scratch. ### Ages 11 to 15 Approximate an arch with straight pieces in Python and watch the total creep up as the pieces multiply. ### Ages 15 and up Code Ramanujan's formulas and the arithmetic-geometric mean, measure each error, and test on the semicircle case. ### A real bridge, a modelled arch The span, the elliptical shape and the history come from Cadw's record. The rise is invented and the real arch is not a perfect ellipse, so the lengths describe the mathematics, not the stonework at Dolauhirion. Why Dolauhirion Bridge ## An elegant arch over the Tywi What the Grade I record says. | Record detail | What it says | | --- | --- | | Built | By Thomas Edwards according to the record, marked Thomas Edward 1773; also attributed to William Edwards and dated 1785 by other writers | | Form | A single broad elliptical arch of some 25 m span, 3.6 m wide, rising to a thin crown | | Innovation | Weight-reducing pierced spandrels, introduced by the Rev William Edwards at Pontypridd in 1756 | | Holes | Large circular holes through the spandrels, edged with cut stone | | Setting | Rising high above the Tywi from natural rock abutments | | Status | Listed Grade I and a scheduled monument | Approximations and exact algorithms sit behind satellite orbits, GPS on an ellipsoidal Earth, lens design and the graphics that draw ovals on every screen. Knowing how accurate a formula is, and testing it against a case with a known answer, separates reliable software from lucky software. A Carmarthenshire student who has measured an arch five ways understands that difference. We have no connection with Cadw or Carmarthenshire County Council. The record's content is theirs; the arch model, the calculations and any mistakes are ours.

[High School Mathematics](/courses/complete-high-school-mathematics-mastery)[Python for Teens](/courses/python-complete-masterclass-teens)Adults ### Numerical Python Python for adults, from calculations to testing numerical code. [Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and formulas ## An AI can quote an ellipse formula in seconds. Will it say how accurate it is? A formula without an error estimate is only half an answer. Ask a chatbot for the length of an elliptical arch and it will often give one formula and one number. It rarely says whether that formula is an approximation, how far out it might be, or how to check it against a known case such as a semicircle. A Carmarthenshire learner who has compared five methods and tested each on a semicircle knows the questions to ask. That habit turns an AI answer into a checked one. Proving how accurate an answer is, rather than taking it on trust, is a skill Carmarthenshire teenagers gain by learning to code in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## From Llanelli to Llandovery, online Towns and villages across the county all join the same way. ### Pupil at the keyboard The learner types every line; the teacher watches on the shared screen and steps in when a bug appears. ### Welsh years, WJEC exams A Year 6 in Burry Port or a Year 13 in Carmarthen is placed by school year and Curriculum for Wales stage, and exam study follows WJEC. Lessons are in English. ### First lesson, no charge A complete lesson for free, followed by an honest view of what fits. ### Level-matched classes Five to ten learners at one level in each class, from different places. ### Term-time rhythm Two lessons weekly during term, none in the holidays. ### Spring and autumn clock changes Twice a year the clocks move, but your class stays at its UK time; the teachers, working on India time, shift their day. Why groups span the county Five learners at one level, free at the same time, rarely live in one Carmarthenshire town. Grouping by level gives a pupil in Tumble or Glanaman a class that fits. Fees ## Fees in Carmarthenshire A learner in Llandeilo pays exactly what one in Llanelli pays, and the same as learners in every country outside India. First class**USD 0** A full lesson, free, then a recommendation. Group tuition**USD 100** About eight lessons a month in a group of five to ten. Private tuition**USD 150** About eight lessons a month with a teacher of your own. We quote only US dollars, never sterling. An invoice follows only after the trial, when a course and weekly slot are settled, and our pricing page explains what happens over holidays, after absences and when changing format.

The 2021 census counted 187,897 usual residents in Carmarthenshire. ### What are the largest towns in Carmarthenshire? ONS 2021 built-up areas: Llanelli 42,155, Carmarthen 16,455, Ammanford 8,285, and Cross Hands and Pen-y-groes 6,340. ### What is the Dolauhirion Bridge project? Learners measure a half-ellipse arch with a 25 metre span in Python, comparing rough formulas, straight-line pieces, Ramanujan's formulas and an exact method based on the arithmetic-geometric mean. ### Why is there no simple formula for an ellipse's perimeter? Its exact length needs what mathematicians call an elliptic integral, so people use very good approximations, such as Ramanujan's, or fast exact algorithms. ### How old is Dolauhirion Bridge? Cadw notes it is marked Thomas Edward 1773, with some writers dating it to 1785, and lists it at Grade I. ### Are lessons held in Carmarthenshire? There is no classroom to travel to: a Glanaman pupil and a Llangennech pupil both join from home by video. ### Do you teach A level maths in Wales? Yes, with WJEC GCSE Computer Science and GCSE maths too. We build understanding and never promise grades. ### What ages can learn? Six-year-olds start with blocks; teenagers move to Python and exam maths; adults up to 67 learn Python at their own pace. ### How much are lessons? Free for the first lesson; after that, a monthly USD 100 in a group or USD 150 individually. ### Do lessons pause in school holidays? Yes. Tell us your school's holiday weeks and we leave them free.
