Coding classes in Bangor, Wales

What are the best coding classes in Bangor, Wales?

Gwynedd, the county that includes Bangor, had 117,393 usual residents at the 2021 census, and in the Bangor City area 60.7% of residents aged five and over were students. Menai Heritage records that Thomas Telford's suspension bridge over the Menai Strait was completed on 30 January 1826. Bangor learners aged six to sixty-seven join our teachers in India on live video, one to one or in a group of five to ten at the same level, at hours arranged around the Welsh school and working day. Lesson one costs nothing; from then on, families pay USD 100 a month for a group place or USD 150 for a teacher to themselves.

Across the Menai Strait from Bangor, the Met Office station at Valley on Anglesey has counted hours of sunshine every month since the 1930s. In November 2001 it swapped its Campbell-Stokes sunshine recorder for an automatic Kipp and Zonen sensor. The record shows fewer sunny hours afterwards. Did Anglesey get duller, or did the new instrument simply count differently? Our teenagers use regression discontinuity: fit a line to the months just before the switch and another to the months just after, and measure the step between them. At every width they try, the step is downward, from 10.8 to 19.5 hours a month. Then they test whether an ordinary month could produce a step that big.

Facts last verified 23 September 2026. Teaching is online; no Bangor branch is claimed.

Students in the centre

In the Bangor City area, 5,082 of the 8,375 residents aged five and over were studying, and 2,261 people lived in communal establishments such as halls.

Young adults

Across Gwynedd, 7.3% of residents were aged 20 to 24 in 2021, against 6.0% in Wales, and 23,962 of the 112,045 aged five and over were students.

Room to spare

At 46.3 residents per square kilometre, Gwynedd is far more thinly settled than Wales as a whole, with 113,682 people living in households.

Our Bangor groups draw on the city and the villages around it. One evening might bring together a Maesgeirchen eight-year-old on a first game, a Bangor Year 11 student working towards WJEC GCSE Computer Science and a Tregarth parent picking up Python for the office, each in a small group at their own pace.

The Menai Strait

A bridge that joined Anglesey to the mainland

From Menai Heritage, the trust that records the bridges over the Menai Strait.

10 August 1819

After an Act of Parliament, the first stone of Thomas Telford's suspension bridge was laid, part of his work on the road between London and Holyhead.

30 January 1826

The Menai Suspension Bridge was completed. Menai Heritage records that sixteen huge chains held up 579 feet of deck, leaving 100 feet of clear space beneath.

The Britannia Bridge

A second crossing followed, the Britannia Bridge engineered by Robert Stephenson, which Menai Heritage records alongside Telford's bridge and the people who built them.

Menai Heritage describes Telford's bridge as the biggest suspension bridge in the world at the time. We have no connection with Menai Heritage, Gwynedd Council or the Met Office. The bridges are on this page because the Valley weather station stands on Anglesey, the island they reach, and because a bridge, like a new instrument, changes what happens on one side of a line and not the other.

Where the sunshine data comes from

The Met Office publishes historic station data for Valley, 10 metres above sea level on Anglesey, with monthly sunshine totals. It marks hours measured by the automatic Kipp and Zonen sensor with a # and says the rest came from a Campbell-Stokes recorder.

Signature project

Did the sunshine change, or did the instrument?

Regression discontinuity looks for a sudden step at a known cut-off. Fit a trend on each side of the cut, using only months close to it, and measure the gap where the two lines meet the cut.

Valley, Anglesey: step in monthly sunshine (hours above or below that month's usual level) at the November 2001 switch to an automatic sensor
Months used on each sideStep at the switch
36-17.2 hours a month
60-18.1 hours a month
84-10.8 hours a month
120-19.5 hours a month

1. Remove the seasons

Subtract each calendar month's average from the Campbell-Stokes years, so a dull December and a bright June can sit on the same line.

2. Fit either side

Take the months just before November 2001 and fit a straight line; do the same just after. The difference between the lines at the cut is the step.

3. Try other widths

A real effect should not vanish when you use a few more or fewer months. At Valley, every width gives a fall, between 10.8 and 19.5 hours a month.

Could an ordinary month do that?

We repeated the fit at 908 other months where nothing changed, placebo cut-offs, using 60 months each side. Their steps averaged almost zero, but 14.0% were at least as large as the real one. So the fall at the switch is consistent with the new sensor counting fewer hours, yet about one ordinary month in seven could show a step that big by chance. That is evidence, not proof. For contrast, at Camborne in Cornwall, which switched in July 2007, the step changed sign with the width and 60% of placebo cuts were as large: no sign of an effect at all.

A plain before-and-after average tells a similar but blunter story: sunshine was 3.9 hours a month above normal in the five years before the switch and 7.0 below it in the five years after. The regression discontinuity is better because it looks only at the months nearest the change and allows for any slow trend, and the placebo test says honestly how surprising the step is.

Breaks in records

Five questions before blaming a change

Learned on Anglesey's sunshine, then used for policy changes, new school rules, price changes, software releases and any record where the method of measuring changed.

Decisions behind a regression discontinuity
QuestionFor Valley's sunshineWhat goes wrong if you skip it
Is the cut-off known in advance?Yes: the file marks the switchHunting for the month with the biggest step
How many months each side?36, 60, 84 and 120, all reportedA width chosen for the answer it gives
What about seasons and trends?Monthly averages removed, lines fittedA slow trend mistaken for a step
Could chance do it?908 placebo cut-offsOrdinary variation reported as an effect
Does a second case agree?Camborne tested the same wayOne station treated as the whole story

The first row is what makes the method trustworthy here. Because the Met Office marks exactly when the instrument changed, the cut-off was fixed before looking at any sunshine figures. Searching the record for the most dramatic step and then explaining it would be a different, far weaker kind of evidence.

Younger learners

Coding and AI

AI models learn from long records. Why should a Bangor teenager hunt for a break in one?

Because a change in how data was collected can look exactly like a change in the world, and models cannot tell the difference on their own.

If an AI system learned Anglesey's weather from this record without knowing about the new sensor, it could conclude the island had become duller in 2001. A learner who has tested the switch directly knows to ask how any dataset was collected, and when that changed, before trusting what a model learns from it.

Regression discontinuity is also one of the most respected ways to measure cause and effect without a controlled experiment. Practising it on a real, well-documented instrument change, with placebo tests to keep it honest, builds the kind of judgement that AI tools cannot supply for you.

So a Bangor teenager should keep learning to code in 2026, beside a strait that Telford bridged two centuries ago: data will keep pouring in, but someone has to notice when the way it was measured changed. The longer argument is in why coding is worth learning in 2026.

FAQ

Bangor coding class questions

What Bangor families ask us most often.

How many people live in and around Bangor?

Census 2021 counted 117,393 usual residents in Gwynedd, the county that includes Bangor. The middle-layer areas the House of Commons Library names Bangor City and Bangor South had 8,615 and 8,377.

How does Gwynedd compare with Wales?

It is thinly settled, at 46.3 residents per square kilometre against 149.9, and has more young adults: 7.3% of residents were aged 20 to 24 in 2021, against 6.0% in Wales. In the Bangor City area, 60.7% of residents aged five and over were students.

What is regression discontinuity?

A way to measure the effect of a change that happens at a known cut-off. You fit a trend just before the cut and another just after, and the gap between them at the cut estimates the effect, then you test whether ordinary points could produce a gap that big.

Did the new sensor at Valley change the sunshine figures?

The record steps down at the November 2001 switch at every width we tried, by 10.8 to 19.5 hours a month, which fits a sensor that counts fewer hours. But 14.0% of placebo months showed a step as large, so it is evidence rather than proof.

Where does the sunshine data come from?

From the Met Office's historic station data for Valley on Anglesey, monthly since December 1930, which marks months measured by the automatic Kipp and Zonen sensor.

When was the Menai Suspension Bridge built?

Menai Heritage records that the first stone was laid on 10 August 1819 and the bridge was completed on 30 January 1826, designed by Thomas Telford. We are not connected with Menai Heritage.

When do Bangor lessons take place?

Bangor families usually choose an after-school slot, a weekday evening or a weekend morning, and we agree it in the free lesson. For our teachers in India the clock reads four and a half hours later than in Wales during British Summer Time, and five and a half hours later in winter.

Is there a centre in Bangor?

No. We have no Bangor centre and no premises anywhere in the UK, as every lesson is live online. Learners need a computer with sound and a steady connection, and our phone number is Indian.

How much do Bangor lessons cost?

The first lesson is free. After it, 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 teaching on the same timetable is USD 150 a month. Nothing is charged until the course, format and time are agreed.

How are learners grouped?

By level, pace and goals rather than age or where they live, with five to ten learners at the same stage. If no group suits the learner's week, we offer one-to-one lessons.
