Maths Tuition in Glasgow | National 5 to Advanced Higher

In short

We teach maths live online to Glasgow learners aged 6 to 67: primary maths from P1 to P7, S1 to S3 maths in the broad general education, then SQA National 5, Higher and Advanced Higher Mathematics, plus adult refreshers. Classes hold five to ten learners at one level, or a learner can work one to one. Our Glasgow example is the Subway: a least-squares circle through its 15 stations has a radius of 1,600.1 metres, but the stations lie between 1,304.4 and 1,891.5 metres from its centre, a good test of the Higher Maths equation of a circle. A first lesson is free; ongoing places are USD 100 a month in a group or USD 150 a month one to one.

National 5, Higher and Advanced Higher maths for Glasgow learners

Scotland has its own curriculum and exams. A Glasgow pupil does not sit GCSEs or A levels; those belong to the English system. Here is the Scottish route, and what our lessons focus on.

Maths stages in Scotland, and our focus at each one
Stage	Usual ages	Our focus
P1 to P3	5 to 8	Counting, place value, adding and subtracting with confidence, shape and pattern.
P4 to P7	8 to 12	Times tables, fractions and decimals, measure, and explaining a strategy aloud.
S1 to S3	11 to 15	Algebra, ratio, angles, Pythagoras and handling data in the broad general education.
National 5	14 to 16	SQA National 5 Mathematics: algebra, geometry including arcs and sectors, trigonometry and statistics.
Higher	15 to 17	SQA Higher Mathematics: straight lines, circles, functions, calculus and vectors.
Advanced Higher	16 to 18	Further calculus, complex numbers, matrices, proof and series.
Adults	18 to 67	Rebuilding confidence, returning to National 5 or Higher, or maths for work.

National 5 maths tutor

SQA National 5 Mathematics (course code C847 75) sits at SCQF level 5. Its course specification lists, among much else, the "Relationship in a circle between the centre, chord and perpendicular bisector" and "Calculating the length of an arc". Both appear in our Subway project below.

Many learners who struggle at National 5 have one shaky foundation, usually fractions or algebraic manipulation. We find it in the trial lesson and fix it before anything else.

Higher and Advanced Higher maths tutor

Higher Mathematics (C847 76) sits at SCQF level 6. The specification asks candidates to be "determining and using the equation of a circle" and to use "properties of medians, altitudes and perpendicular bisectors" with straight lines. Advanced Higher Mathematics (C847 77) at SCQF level 7 goes on to deeper calculus, complex numbers and proof.

Our national pages go further: National 5 maths, Higher maths and Advanced Higher maths.

Sources: National 5 Mathematics course specification and Higher Mathematics course specification, read on 1 October 2026. The awarding body's site now shows both the names Qualifications Scotland and SQA. Age ranges are typical, not rules.

The Glasgow project

Is the Glasgow Subway really a circle?

Fifteen stations, one loop. The question is simple enough for P7 and deep enough for Higher, and it has a numerical answer.

On 1 October 2026 we downloaded the 15 Subway stations from OpenStreetMap, the volunteer-built map. We turned each station's latitude and longitude into flat coordinates in metres, which is accurate enough over a few kilometres, and then asked a computer for the circle that sits closest to all 15 points at once.

That fitted circle has a radius of 1,600.1 metres. Its centre lands roughly 100 metres from a postcode in the G3 district. Measured from that centre, St George's Cross is the closest station at 1,304.4 metres and Partick the furthest at 1,891.5 metres.

So the loop bulges in some places and pinches in others. The typical station sits about 176 metres off the fitted circle (root mean square 195.8 metres), roughly a ninth of the radius. Round enough to call it a circle in conversation; not round enough to call it one in a maths lesson.

There is a nice check on that. Join the stations in order with straight lines and the 15-sided shape has a perimeter of 10,261 metres. Divide by the fitted diameter and you get 3.206. For a true circle that ratio would approach π, and 3.206 is a surprisingly good guess at 3.14159 from a railway map.

Distance of selected stations from the centre of the fitted circle, our calculation from OpenStreetMap
Station	Distance from centre	Off the circle by
St George's Cross	1,304.4 m	295.8 m inside
Kinning Park	1,333.8 m	266.3 m inside
Kelvinbridge	1,384.0 m	216.1 m inside
Ibrox	1,645.0 m	44.9 m outside
Buchanan Street	1,775.5 m	175.4 m outside
Bridge Street	1,839.8 m	239.7 m outside
Partick	1,891.5 m	291.4 m outside

Data: OpenStreetMap contributors, nodes tagged as Subway stations in Glasgow City, one Overpass query on 1 October 2026. Station positions are mapped points, not platform centres. The fitted circle, distances and ratios are Modern Age Coders' calculations; they are not published by SPT and they are not track lengths.

Higher Maths, on a real map

The equation of the Subway circle, and the circle through three stations

Put the origin at Buchanan Street, measure in kilometres with east as x and north as y, and the fitted circle has an equation a Higher candidate can read at a glance.

Centre and radius

With that origin, our fitted circle has centre (−1.775, −0.058) and radius 1.600, both rounded to the nearest metre. In the form Higher uses, that is (x + 1.775)² + (y + 0.058)² = 1.600². Expanded, it becomes x² + y² + 3.549x + 0.117y + 0.592 = 0, and a learner can work backwards from the expanded form to the centre and radius, which is a classic exam step.

Substitute a station into the left-hand side and the sign tells you which side of the circle it is on: negative inside, positive outside. Govan, at (−3.570, −0.018), gives a positive answer, so it lies outside, which matches the table above.

Three stations, one circle

Any three points that are not in a straight line lie on exactly one circle. Its centre is where the perpendicular bisectors of two chords meet, the idea National 5 states and Higher puts to work. Choose different trios of stations and you get different circles.

Hillhead, St Enoch and Cessnock give a radius of 1.602 km, almost identical to our fitted circle. Govan, Buchanan Street and Shields Road give 1.831 km. That spread is the clearest possible evidence that the stations are not on one circle: if they were, every trio would agree.

Circles through three Subway stations, found from perpendicular bisectors (our calculation)
Three stations	Radius, km
Hillhead, St Enoch, Cessnock	1.602
Partick, Cowcaddens, Kinning Park	1.599
Kelvinbridge, Bridge Street, Ibrox	1.625
Govan, Buchanan Street, Shields Road	1.831
Least-squares fit to all 15	1.600

Arc length gives a National 5 version. Seen from the centre, neighbouring stations are on average 24.0° apart. The widest gap, Shields Road to Kinning Park, is 33.4°, an arc of about 933 metres on the fitted circle; the narrowest, Partick to Kelvinhall, is 14.8°, about 413 metres. Learners compute those with (angle ÷ 360) × 2πr, and then discuss why an arc is not the same as the tunnel between two stations.

All coordinates, equations and arcs are our calculations from the OpenStreetMap download above, rounded as shown. SQA wording from the Higher Mathematics course specification.

Maths beyond lessons

Masterclasses, Maths Circles and the Scottish Mathematical Challenge

Glasgow has a lot going on for learners who enjoy maths. These details come from the University of Glasgow's public engagement page; we take part in none of it.

Royal Institution Masterclasses

The page says the Strathclyde Series "is hosted by the University of Glasgow. It runs for 6 weeks in the autumn term, starting at the end of October." Each Saturday morning brings a different speaker.

Maths Circles

Run with the charity We Solve Problems "for motivated pupils from P7-S4". The page adds that they "take place on Saturdays throughout the academic year and are free to attend (booking is required)".

Scottish Mathematical Challenge

The page notes it "celebrated its 50th anniversary in 2026", with Junior (S1 and S2), Middle (S3 and S4) and Senior (S5 and S6) divisions, and a separate primary competition run by the University of Strathclyde.

The university page explains how to book each of these. A learner who loves problems would get a great deal from the Maths Circles, which are free.

UK-wide competitions, such as the UK Mathematics Trust challenges, are open to Scottish schools too. Our competitions calendar keeps the dates in one place.

Our own teaching is live on video, so a learner in Partick, Shawlands or Dennistoun joins from home. Groups are formed by level, which means a Glasgow learner may share a class with someone in Edinburgh, Aberdeen or further afield.

The Subway project is good practice for challenge papers: it rewards a clear argument, such as the point that every trio of stations would agree if the loop were truly a circle.

Adult learners

Maths tuition for adults in Glasgow

Plenty of our learners are adults: some returning to a qualification, many simply wanting maths to make sense at last.

From the beginning

Number, fractions, percentages and simple algebra, taken slowly and explained properly, without anyone watching the clock.

Back to National 5 or Higher

For college entry, a change of career or personal satisfaction. We follow the SQA course specification and use past-paper style questions.

Maths at work

Spreadsheets, rates, percentages and charts. Our adult maths page explains how adult groups run.

Adults often light up at the Subway project, because so many have ridden the loop for years without ever asking how round it is. Ten minutes with a coordinate grid turns a familiar journey into a piece of geometry they can explain to anyone.

The route

From counting to circle equations, in four steps

Each step relies on the one before. A learner enters at whatever step fits, which the free lesson reveals.

Four steps through Scottish school maths, with a sign that each is secure
Usually	Step	Secure when the learner
P4 to P7	1. Number and measure	Converts between units and explains each step of a calculation
S1 to S3	2. Algebra and shape	Solves linear equations and uses Pythagoras on a coordinate grid
S4	3. National 5 geometry	Finds an arc length and the centre of a circle from two chords
S5 and S6	4. Higher reasoning	Writes and interprets the equation of a circle from given information

Joining in S4 or S5

It is not too late. We secure algebra first, because almost every Higher question leans on it, then build up the geometry.

If the gap is larger than the months left, we will say so plainly after the trial.

Beyond Higher

Some learners continue to Advanced Higher; others try statistics and probability or maths through coding, where a short program fits the Subway circle for them.

A few discover problem solving and head for competition maths.

Glasgow maths questions

Questions Glasgow families and adult learners ask

What is the equation of a circle?

A circle with centre (a, b) and radius r has equation (x − a)² + (y − b)² = r². It comes from Pythagoras: every point on the circle is exactly r from the centre. SQA Higher Mathematics also uses the expanded form x² + y² + 2gx + 2fy + c = 0.

How much does a maths tutor cost in Glasgow?

The trial lesson is free. After that a group place is USD 100 a month and one to one lessons are USD 150 a month, with no extra fees.

Are you a National 5 maths tutor?

Yes. We teach National 5 Mathematics, steering lessons to the SQA course specification and practising the kinds of question the course assessment uses.

Do you offer Higher and Advanced Higher maths tutoring?

Yes, both. Higher covers straight lines, circles, functions, calculus and vectors; Advanced Higher adds further calculus, complex numbers, matrices and proof.

Which school year is best for starting a maths tutor?

Whenever a learner first starts to feel lost, before the gap grows. We teach from P1 age through to adults of 67.

Is online maths tuition as good as face to face?

For most learners it works very well: the teacher sees the working appear on screen and corrects it straight away. Every lesson is live with a real teacher, and groups keep the same teacher.

Do you teach GCSE or A level?

Yes, for learners in the English system. Glasgow pupils normally sit SQA qualifications, so for them we teach to National 5, Higher and Advanced Higher instead.

Do you teach adults in Glasgow?

Yes, from first steps to National 5 and Higher, in adult groups or one to one.

Can you guarantee an A at Higher?

No. Nobody can honestly guarantee a grade. We teach thoroughly and keep you informed about progress.

Are you part of the University of Glasgow or SQA?

No. We mention public events and documents so families know about them. We have no link with any university, the awarding body, or any school.
