How a Concours Actually Works, and Why It Is Not Like an Exam

A concours is not an exam you pass. It is a competition you place in. An examination measures you against a fixed standard, so if the standard is 50 and you score 55, you pass, and it makes no difference how anyone else did. A concours has a fixed number of seats. You are ranked against everyone who sat it that year, and the last person admitted sets the line. Score 55 and you may be admitted one year and rejected the next, with no change in your ability at all.

Almost every mistake candidates make follows from missing that single difference. This article explains the mechanism, then what it means for how you prepare.

The two models, side by side

On the left, the line is drawn first and candidates are measured against it. On the right, candidates are ranked first and the line falls wherever the last seat lands. The grey bars on the right are the important part of the picture: those candidates did not fail. They were simply not in the top thirty that year.

Why the cut off changes every year

Because the line is a result rather than a target, it moves with three things, none of which you control.

• How many people sat it. More candidates for the same seats pushes the line up.
• How difficult the paper was. A hard paper depresses everyone’s score, so the line falls. A hard paper is not bad news.
• How many seats were offered. This can change between years by decision, not by demand.

This is why last year’s cut off mark is a weak guide and why the figures circulating on social media are so often misleading. A number that was true once gets repeated for years as though it were a fixed requirement. Treat any cut off you did not read on the institution’s own announcement as a rumour.

It also explains something candidates find genuinely confusing: you can score higher than someone who was admitted last year and still miss out this year. Nothing went wrong. The field was different.

What this changes about preparation

Every mark matters, including on questions you would normally skip

In a threshold exam, once you are safely past the standard, extra marks change nothing. In a concours there is no safe. Two candidates separated by a single mark can be separated by an admission, so the marks you leave on the table because a question looked tedious are marks someone else collected.

The practical consequence: finish the paper. An unattempted question scores zero with certainty, while a half remembered attempt sometimes scores something.

Speed is part of what is being tested

When everyone is ranked, the candidates who complete the paper have a structural advantage over equally able candidates who do not. Working untimed builds knowledge but not the skill actually under assessment.

Practise with a clock from early on, not in the final fortnight. If you consistently run out of time, that is a specific and fixable problem, and it is usually caused by spending too long on the first section rather than by working slowly overall.

The paper is set by one institution, so it has habits

A national examination is written for a whole cohort across many schools. A concours is written by a specific institution, often by the same small group of people, and it develops recognisable patterns: topics that recur, a house style in how questions are phrased, a stable balance between sections.

This makes anciennes épreuves far more valuable here than past papers are for an ordinary exam. You are not only practising the subject, you are learning a particular institution’s habits. Work through several years for the same school and the pattern becomes visible.

The method for using them is the same one that works everywhere: attempt under timed conditions, mark honestly, and turn every lost mark into something you review on a schedule. Our guide to spaced repetition and a twelve week revision plan sets out how to run that review so it actually sticks.

Sitting more than one is normal

Because the line is unpredictable, candidates commonly enter several concours in a season. This is sensible rather than pessimistic, and treating a single attempt as your whole plan puts a year on one unpredictable outcome.

Before counting on a combination, check two things: whether the examination dates collide, and whether the registration windows do. The second catches more people than the first.

The registration deadline is the real hurdle

More candidates are lost at registration than at the paper. Registration typically closes well before the examination, requires documents you may not hold yet, and is announced through official channels that you have to be watching.

Stage	What goes wrong
Announcement	You hear about it late because you were not watching the official channel
Documents	A certificate, attestation or certified copy takes longer to obtain than the window allows
Payment	The prescribed route is not the one you assumed, and proof is required
Submission	The file is incomplete and there is no time left to correct it

Work backwards from the registration deadline rather than the examination date, and start assembling documents before the announcement. The documents are broadly predictable even when the dates are not.

Because requirements and dates change between cycles, confirm every detail with the institution itself in the year you apply. Nothing in this article is a substitute for the official announcement.

Culture générale, and papers with no syllabus

Several concours include a general knowledge paper with no published syllabus, which candidates find impossible to prepare for and therefore do not prepare for. That reaction is what makes it worth preparing for.

You cannot revise everything, but you can do three things. Read past papers to see the range actually asked, since the spread is usually narrower than the absence of a syllabus suggests. Follow national and regional affairs consistently rather than intensively. And practise structuring an answer quickly, because on this paper organisation earns marks that content alone does not.

A preparation sequence that fits the format

1. Find the registration window first. Everything else is planned backwards from it.
2. Collect several years of past papers for the specific school, not for the subject in general.
3. Attempt one untimed to see the shape and the range.
4. List recurring topics across the years you have. This is your priority order.
5. Work through those topics, turning errors into review items rather than moving on.
6. Switch to timed full papers at least two months out, not two weeks.
7. Practise finishing, deliberately, even when it costs quality on the last section.

Choosing which concours to target

Candidates often pick a school by reputation and work backwards from there. That is the wrong order, because the ranked structure means the competitiveness of a school is only loosely related to how hard its paper is.

Three things decide how realistic a target is, and only one of them is your ability.

• Seats relative to applicants. A school offering a modest number of places in a popular field is harder to enter than a stronger school in a field fewer people chase. Where both figures are published, the ratio tells you more than prestige does.
• How well the paper suits you. Two schools testing the same subject can weight it very differently, one favouring breadth and recall, another favouring extended reasoning. Read several past papers before deciding, because a paper that suits your strengths is worth more than a small difference in reputation.
• Whether you can realistically sit it. Location, dates, cost and document requirements all rule options in or out, and they do so early.

A sensible spread is one ambitious target, one realistic target and one you would genuinely accept, with the papers read before you commit rather than after. Building a plan around a single school is the most common reason a candidate loses a whole year to an outcome they could not control.

If there is a second stage

Some concours are decided entirely on the written paper. Others shortlist from it and then run a second stage, which may be an oral, an interview, a practical assessment or a medical check. Where a second stage exists, the written paper is a filter rather than the decision.

This matters for planning because candidates routinely stop preparing the moment the written paper is done, then have very little notice before the next stage. Find out at registration whether a second stage exists for your school, and if it does, assume the gap will be short.

Preparing for an oral is different from preparing for a paper. You are being assessed on how you think aloud under pressure, so practise speaking your reasoning rather than writing it. Explaining a topic out loud to someone who does not study it exposes gaps that silent revision hides completely, and it builds the specific skill the oral tests.

Have a clear, honest answer ready for why this school and why this field. It is asked almost every time, and a vague answer is noticed.

What to do while you wait for results

The gap between sitting a concours and seeing the list is long enough to waste, and candidates commonly stop everything during it.

Two things are worth doing. Keep a light review running on the material, because if you are not admitted the fastest route back is a foundation you did not let decay. And prepare the documents you would need if you are admitted, since acceptance windows after a list is published are often short and administrative delay has cost people places they had already won.

Watch the official channel for the results announcement rather than relying on word of mouth. Lists circulate informally and are sometimes wrong, occasionally in both directions.

Questions candidates ask

Is a high score enough?

Only relative to the field. There is no score that guarantees admission, because the threshold is produced by the results rather than set before them. Aim to be as far up the ranking as you can rather than to reach a number.

Does last year’s cut off tell me anything?

A little. Several years of cut offs show a rough band and how much it moves, which is more useful than any single year. One figure treated as a target is misleading, and a figure passed around on social media may not be real at all.

Should I retake if I miss out?

Many admitted candidates were not admitted on their first attempt. Because the line moves with the field, a near miss one year can become a place the next with modest improvement. Check the rules on repeat attempts for your specific school, since they vary.

How is this different from an entrance exam elsewhere?

The ranked and fixed seat structure is shared with several other systems, including Nigeria’s tertiary entrance route. Our guide to African exam systems explains which bodies issue leaving certificates and which run competitive entrance, because confusing the two is the most common planning error we see.

Where to start

Identify the school you are aiming at and find its official announcement channel this week. Then find as many past papers for that school as you can. The subject knowledge can be built over months, but the registration window cannot be recovered once it closes, and the papers tell you what the months should be spent on.
