Coding classes in Hampshire

What are the best coding classes in Hampshire?

Hampshire is thirteen councils, Portsmouth, Southampton and eleven districts, and 1,857,822 people at the 2021 Census, not counting the Isle of Wight. Southampton and Portsmouth are the two cities; then come Basingstoke, Gosport, Farnborough, Winchester, Andover and Eastleigh, with the New Forest, the South Downs and dozens of towns in between. Our classes cover the whole county identically: live video lessons with teachers in India, learners placed by skill rather than by age, a welcome for anyone from 6 to 67, and a choice between groups of five to ten and one-to-one teaching. We teach programming, Python, AI, data and maths. The Hampshire project comes from the New Forest. You pay nothing for lesson one; after that, USD 100 a month in a group or USD 150 a month privately.

The New Forest National Park Authority says the Forest's landscape is shaped by ponies, cattle and pigs that roam freely, and the Verderers have regulated that commoning since the New Forest Act of 1877. Animals that roam freely pose a problem every ecologist knows: how do you count a population you can never see all at once? One classic answer is almost magical. Mark some animals one day, look again another day, and count how many of the second group carry a mark. From that single number you can estimate the whole population. This page's project builds the method in Python, tests it on a model herd thousands of times, and then shows how one broken assumption can throw the answer out by three-quarters.

Hampshire by the numbers

Thirteen councils, 1,857,822 people and two cities on the Solent

Council totals are 2021 Census counts on Nomis. The towns are ONS built-up areas above 8,000 people, checked against our own addition of census output areas.

The two cities hold under a quarter of the county between them. Portsmouth's built-up area, 223,305 people, reaches over the city boundary into Fareham and Havant; Southampton's runs into Eastleigh. North of them the county is spread across market towns and commuter towns, from Andover and Basingstoke to Farnborough, Fleet and Alton, many of them a long way from the cities' universities and clubs.

Bursledon, with 8,070, completes the list. Every row agrees with our count to within rounding except Emsworth, which has about 1,600 of its 11,505 residents over the border in West Sussex; the table prints the ONS total. Hampshire County Council, Portsmouth, Southampton and academies set school calendars separately, and we did not read them; lesson breaks are agreed with each family.

The Hampshire project

Counting a herd that never stands still

A model herd in Python, two thousand simulated surveys, and the one assumption that the whole method rests on.

We do not know how many animals graze the Forest, and we have not read a published count, so the learner builds a model herd of 3,000, a number we chose. On day one, 300 animals are found and marked. On day two, 300 animals are seen again, some marked and some not. If the herd is well mixed, the share of marked animals among those seen on day two should match the share of the whole herd that was marked. So if 30 of the 300 seen carry marks, a tenth of the herd was marked, and 300 marked animals means about 3,000 in all. That is the Lincoln-Petersen estimate: marked times seen, divided by recaptures.

Our run of 26 September 2026: 2,000 simulated surveys of a model herd of 3,000
Method or situationTypical estimateSpreadWithin 10 per cent of 3,000
Lincoln-Petersen, fair mixingMean 3,089, median 3,00054246.2 per cent of surveys
Chapman's correction, fair mixingMean 3,00350744.9 per cent of surveys
Marked animals half as likely to be seenMedian 5,328Badly too high
Marked animals twice as likely to be seenMedian 1,708Badly too low

Three lessons sit in that table. First, luck matters: recaptures ranged from 13 to 48 across the surveys, so any single estimate can be well off, and fewer than half land within 10 per cent. Second, the obvious formula is slightly biased high, averaging 3,089, because a survey that happens to recapture few marked animals divides by a small number; a small correction due to Chapman, adding one in the right places, brings the average to 3,003.

The third lesson matters most. The whole method assumes marking changes nothing. If marked animals learn to avoid people and become half as likely to be seen, recaptures fall and the estimate balloons to around 5,328, three-quarters too high. If they become easier to spot, it collapses to about 1,708. The mathematics is fine in every case; the assumption is what fails. Real surveys spend much of their effort checking exactly that.

Ages 10 to 13

Mark twenty beans in a jar, shake, draw a handful, count the marked ones, and estimate the whole jar; then check by counting.

Ages 13 to 16

Write the survey in Python, run it two thousand times, and plot how widely the Lincoln-Petersen estimate varies.

Ages 16 and up

Add Chapman's correction, measure the bias of each method, and model marked animals that behave differently.

What is modelled

The herd size, the numbers marked and seen, and the behaviour changes are values we chose to teach the method. The Verderers and the National Park Authority do not describe how animals are counted on the pages we read, and nothing here describes their methods or their numbers.

Why the New Forest

A National Park grazed by animals that roam freely

The Hampshire link, in the words of the organisations that look after the Forest.

Estimating a population you cannot count directly is one of the most useful ideas a learner can meet. The same reasoning estimates fish in a lake, bugs in a program found by two independent testers, and people who are hard to reach in a survey. A Hampshire teenager who has built it, tested it and broken it knows both how powerful it is and exactly where it can go wrong.

Modern Age Coders has no connection with the Verderers of the New Forest, the New Forest National Park Authority or any Hampshire council, and nothing on this page implies one. Their facts are theirs; the model herd and its numbers are ours.

Maths for Data ScienceStatistics & Probability
AI and estimates

An AI can apply a population formula. Will it question the assumption underneath?

Rarely, and the answer looks just as confident when the assumption is false.

Give a chatbot the numbers from a mark-and-recapture survey and it will apply the formula correctly and report a population with a neat margin of error. It will not usually ask whether marking changed the animals' behaviour, whether the herd mixed between surveys, or whether the two days saw the same area. Those are the questions that decide whether the answer is 3,000 or 5,300, and they are questions about the world, not about arithmetic.

A Hampshire student who has watched a single behavioural change push the estimate three-quarters too high will ask about assumptions before trusting any number, whether it comes from a survey, a model or an AI. That habit is the core of good science and good data work, and it is exactly what a fluent machine answer tends to skip.

So a Hampshire teenager should learn to code in 2026 to be able to test the assumption, not just run the formula. The longer argument is in why teenagers should still learn to code in 2026.

Getting started

Tadley to Lymington without the M3

Hampshire is large and its roads are busy at school pick-up time. Online lessons remove every mile.

From home

A bedroom in Alton, a kitchen in Hedge End, a desk in Yateley. The teacher shares a screen and the learner writes the code.

English and school terms

Year groups, GCSE options and A levels are named as Hampshire schools name them, and every lesson is in English.

Free first lesson

A proper lesson of real work, then an honest suggestion of level and course. There are no card details to give.

Classmates at your stage

Groups of five to ten learners who have reached the same point, gathered widely, so the lesson suits each of them.

Breaks with your school

Two lessons a week for most learners, stopping when their own school stops.

All times in UK time

Our teachers keep India time, four and a half hours ahead in UK summer and five and a half in UK winter; every booking is written in UK time.

Why groups are formed by level

Thirty-five towns and two cities spread across a large county mean few places have enough learners at one stage on one evening. Level-based groups let a Petersfield learner and a Gosport learner share a class.

Fees

Hampshire fees

The same prices across the whole county, and in every country apart from India.

First classUSD 0

A full lesson of genuine work, ending with a recommended level and course.

Group tuitionUSD 100

Roughly eight lessons a month, in a group of five to ten at one level.

Private tuitionUSD 150

Roughly eight lessons a month with one teacher and one learner.

All fees are in US dollars for families outside India, with no pound list. You are charged only after the free lesson has settled a course and a weekly slot; the pricing page explains pausing, missed lessons and changing between group and private teaching.

FAQ

Hampshire questions

On the county, the New Forest project and how lessons work.

How many people live in Hampshire?

Portsmouth, Southampton and the eleven Hampshire districts held 1,857,822 usual residents at the 2021 Census, from ONS figures on Nomis. That total does not include the Isle of Wight.

What are the largest towns in Hampshire?

By ONS built-up area: Southampton 249,620, Portsmouth 223,305, Basingstoke 117,210, Gosport 70,110 and Farnborough 60,655. The page lists thirty-five Hampshire towns above eight thousand.

What is the herd counting project?

Learners mark some animals in a model herd, look again, and estimate the total from how many marked animals reappear. They test the Lincoln-Petersen and Chapman estimates over 2,000 simulated surveys and see what happens when marking changes behaviour.

What is capture-recapture?

A way to estimate a population you cannot count directly: mark some individuals, sample again, and use the share of marked ones in the second sample to scale up to the whole.

Who looks after the New Forest?

The Verderers, a body set up under the New Forest Act of 1877, regulate commoning; the New Forest National Park Authority, since 2005, looks after the National Park, which covers 220 square miles.

Is there a classroom in Southampton or Portsmouth?

No. All teaching is live online, so a learner in Andover and one in Hayling can be in the same class without travelling.

What ages do you teach?

Six to sixty-seven. Block coding for young children, typed Python from about ten, AI and data for teenagers, and maths for data science or Python for adults. The free lesson finds the level.

Do you teach machine learning to teenagers?

Yes. The teen AI and machine learning course covers Python, real ML models, neural networks, computer vision, language processing and generative AI.

How much are lessons?

No charge for the first lesson. Continuing is USD 100 a month for a group or USD 150 a month for private lessons, with nothing to pay to join and no minimum term.

When are Hampshire school holidays?

Hampshire County Council, Portsmouth, Southampton and academies set their own dates. We fit lesson breaks around your school's calendar.
