Which Maths Olympiad Should My Child Take?
A parent guide to the AMC and UKMT challenges by year group - what each one punishes, and how to test readiness in an afternoon.
Parents usually arrive at this question the same way: a school sends home a form, a friend mentions a competition, and suddenly there is a decision to make with no obvious basis for making it. If you are wondering which maths olympiad your child should enter, the honest answer is that it depends on two things only - their school year, and whether they have ever sat a timed competition paper before.
This guide sets out the realistic options by age, what each one actually involves, and how to test the decision in an afternoon rather than committing blind.
Start with the year group, because most competitions are age-gated
| School year | Natural entry points |
|---|---|
| Years 7-8 (Class 6-8) | AMC 8, UKMT Junior Mathematical Challenge |
| Years 9-11 (Class 9-10) | AMC 10, UKMT Intermediate Mathematical Challenge |
| Years 12-13 (Class 11-12) | AMC 12, UKMT Senior Mathematical Challenge |
That table answers which maths olympiad is open to your child; the rest of this guide covers which is the better fit. The UKMT challenges are open by year group: Junior for Year 8 and below, Intermediate for Year 11 and below, Senior for Year 13 and below. The AMC 8 is for grade 8 and below, the AMC 10 for grade 10 and below, and the AMC 12 for grade 12 and below. A student eligible for two will normally sit the lower one first.
The real difference is not difficulty - it is what the paper punishes
This is the part almost nobody explains to parents, and it matters more than the syllabus. Each competition marks differently, and those rules change what a sensible student does in the hall.
- AMC 8 - one mark per correct answer, nothing deducted for a wrong one. Every question should be answered. Nothing to fear here: a guess costs nothing.
- UKMT Junior - 5 or 6 marks per question, no penalties anywhere. Again, answer everything.
- AMC 10 and 12 - 6 for correct, 0 for wrong, and 1.5 for a question left blank. A blind guess averages 1.2, so guessing without thinking actually loses marks.
- UKMT Intermediate - no penalty on the first fifteen questions, then 1 mark deducted on questions 16-20 and 2 on questions 21-25.
- UKMT Senior - 4 for correct, 1 deducted for wrong, on every question.
A child who learns "always answer everything" on the AMC 8 and carries that into the AMC 10 three years later will lose marks for a reason that has nothing to do with mathematics. Knowing which paper your child is sitting, and what it punishes, is worth more than an extra month of revision.
Is my child ready?
Once you know which maths olympiad matches the year group, readiness is the next question - and the useful test is not a syllabus checklist. It is one timed paper, sat cold.
Competitions of this kind do not test curriculum knowledge - a Year 8 student has already met almost every technique the Junior Challenge uses. What they test is recognition: seeing that a problem about handshakes is really a counting problem, when nothing on the page says so. School mathematics announces its topic at the top of the exercise; a competition paper never does.
That is why a child who scores well in school maths can find their first competition paper bruising, and why that first paper is the only honest readiness test there is. A free full mock takes forty to sixty minutes and settles the question.

Reading the result without over-reading it
A first cold score is a starting point, not a verdict. What to look for:
They finished, with a modest score. Good. Pace is fine and the gap is recognition, which practice fixes quickly.
They ran out of time halfway. Very common and not a problem. It means they are treating the paper as a queue and working every question in order. That is a strategy fix, not a mathematics one.
They could not start most questions. The competition is a year too early. Try the level below, or spend a term on problem-solving before entering. This is a genuinely useful thing to learn in an afternoon rather than on the day.
What a first score is not is a measure of ability. Nearly every student's first competition paper is worse than their school marks suggest, and that says more about the format than about them.
Does any of this matter beyond the certificate?
Fairly asked. For most students the honest benefit is the thinking: competition problems reward persistence with an unfamiliar situation, which school assessment rarely does.
Beyond that, it depends on the destination. For US university applications, AMC performance and AIME qualification are understood signals for mathematics and engineering courses. In the UK, UKMT results and follow-on rounds like the Olympiad papers carry weight for mathematics admissions alongside the MAT and STEP. For most other paths the certificate matters little and the habit of thinking matters a lot.
What we would not claim is that a competition is necessary. A child who dislikes timed mathematics and is pushed into it usually learns to dislike mathematics.
A sensible first year
Term 1 - find out where they are. One free cold paper. Read the result using the guide above. Do nothing else.
Term 2 - build the two skills the paper tests. Topic-wise practice while a method is new, then mixed papers so they practise recognising it without being told. Keep a log of why marks were lost, by cause rather than by topic.
Term 3 - rehearse. Two or three full papers at competition timing, with the marking scheme applied properly so the score means something.
Our practice series cover all six competitions - 120 papers and 3,450 questions with worked solutions - and seventeen of those papers are free. Our guide to the free papers lists them and explains how to use them.
When teaching helps and when it does not
If the error log keeps naming the same cause after three papers - cannot set up a counting argument, never sees the auxiliary line - more papers will keep confirming the gap rather than closing it. That is when a teacher is worth the money, and not particularly before.
Our courses run live small-group and one-to-one sessions built around what a student's own log exposes. We would rather a family worked the free papers first and came to us with evidence than paid for a term on a hunch.
The short version
Pick by year group, then find out where your child actually is with one free timed paper. Learn what your competition punishes, because the right instinct on one paper is the wrong one on another. Treat a low first score as information rather than a verdict. And if the same problem keeps recurring after a few papers, that is the moment teaching pays for itself.

Questions people ask
Which maths olympiad should a Class 6 or Year 7 student take?
The AMC 8 or the UKMT Junior Mathematical Challenge. Both are open to students well below their upper age limit - AMC 8 for grade 8 and below, Junior Challenge for Year 8 and below - so a Year 7 student is comfortably in range. Neither deducts marks for a wrong answer, which makes them a gentle first competition.
How do I know if my child is ready?
Have them sit one full timed paper cold, before any preparation. If they finish with a modest score, they are ready and the gap is recognition. If they run out of time halfway, that is a pacing strategy issue, not a readiness one. If they cannot start most questions, the competition is a year early - try the level below.
What is the difference between the AMC and the UKMT challenges?
The AMC is the American series, the UKMT challenges are British, and both are open internationally through schools. The main practical differences are the marking schemes and the follow-on routes: strong AMC scores lead toward the AIME, while UKMT results lead to the Kangaroo papers and the Mathematical Olympiads. Many students sit both.
Do maths olympiads help with university admissions?
For mathematics, engineering and computer science, yes - AMC performance and AIME qualification are understood signals in US applications, and UKMT results carry weight for UK mathematics admissions alongside the MAT and STEP. For most other courses the certificate matters little, though the problem-solving habit matters regardless.
When should a child start preparing?
A term before the paper is plenty for a first attempt, and much of the early gain is strategic rather than mathematical - learning the marking, the pacing, and how to recognise a problem type. Students aiming at follow-on rounds benefit from a longer run, typically eight to twelve weeks of structured work.
