How to Qualify for the Math Olympiad from Bangladesh (IMO Guide)

The Bangladesh Math Olympiad (BdMO) is the only route from Bangladesh to the International Mathematical Olympiad. You register free with BdMO, pass the online selection round, then the regional olympiad, then the national olympiad, and finally earn a place in the national camp. Six students are chosen from that camp to represent Bangladesh at the IMO each year.

Any school or college student up to Class 12 can enter, and the first round costs nothing. This guide walks through each stage of the Bangladesh math olympiad selection process, who is eligible, when registration opens, and how to prepare for the rounds that actually eliminate people.

How to Participate in the Math Olympiad in Bangladesh

Participating starts with registration on the official BdMO site, not with an invitation. Nobody nominates you and your school does not need to apply on your behalf, which is the most common misunderstanding among students asking how to join the math olympiad in Bangladesh.

The full path runs through four stages before the international final.

Stage	Who takes it	Format	What it decides
Online selection round	Everyone who registers	Online, taken from home	Who advances to the regional round
Regional olympiad	Selected students	Offline, at a divisional venue	Who advances to the national round
National olympiad	Regional winners	Offline, national venue	Who enters the national camp
National camp	Top national scorers	Residential training plus tests	The six-member IMO team
IMO	The six selected students	Six proof problems over two days	Individual and team medals

Step 1: Register for BdMO

Registration is free and open to every student, and you have to register again each year even if you took part before. Previous participation does not carry over.

Sign up through the official Bangladesh Mathematical Olympiad site at matholympiad.org.bd, using the online registration portal linked there. Confirm the current year’s dates on that site before planning around them, since the calendar shifts from year to year.

Step 2: Pass the Online Selection Round

The first round is now taken online rather than at a venue. It filters a very large entry pool down to the students who go on to the regional stage, so treat it as a real round rather than a formality.

Questions at this stage are short-answer and lean on speed and accuracy more than full proofs.

Step 3: Compete in the Regional Olympiad

Regional olympiads are held offline at divisional venues across Bangladesh. Students selected from the online round sit this paper, and the top performers in each region are invited to the national olympiad.

Difficulty steps up here, with more number theory and combinatorics than most school syllabuses cover.

Step 4: Compete in the National Mathematical Olympiad

The National Mathematical Olympiad brings together regional winners from every division. This paper tests advanced problem solving across algebra, geometry, number theory and combinatorics, and written reasoning starts to matter as much as the final answer.

Top scorers at the national olympiad are invited into the camp.

Step 5: Earn Your Place in the National Camp

The camp is where the six-member team is actually decided. Students receive intensive coaching from past olympiad participants, university faculty and subject experts, and sit repeated selection tests throughout.

Performance across those camp tests, not the national olympiad score alone, determines who goes to the IMO.

Who Can Participate? IMO Eligibility and Age Limit

Any school or college student in Bangladesh up to Class 12 can register for BdMO, and the International Mathematical Olympiad itself requires that competitors are under 20 years old and have not started at a university or equivalent institution. There is no minimum score, no prior qualification and no fee for the first round.

So the practical eligibility rules look like this:

• Class range: school and college students up to Class 12
• Age limit for the IMO: under 20 on the day of the competition, as set by the IMO Board
• University students: not eligible, since entrants must not have enrolled in tertiary education
• Cost: the first round is free
• Re-entry: you can compete in multiple years while you remain eligible

Is the IMO only for high school students? Effectively yes at the international level, because the age and enrolment rules rule out university students. But BdMO runs categories for younger students too, so you do not have to wait until Class 11 to start competing. Starting in middle school is normal among students who eventually make the team, and our junior math olympiad guide covers where to begin.

Master the Four Core Topics

Olympiad problems draw on four areas, and only one of them overlaps much with the national curriculum. Knowing which topic a problem belongs to is often half the work of solving it.

Algebra

• Polynomials and their properties
• Inequalities such as AM-GM and Cauchy-Schwarz
• Functional equations

Geometry

• Triangle and circle theorems
• Coordinate geometry
• Trigonometry applied to problem solving

Number Theory

• Prime numbers and divisibility rules
• Modular arithmetic and congruences
• Diophantine equations

Combinatorics

• Counting principles and the binomial theorem
• Graph theory basics
• The pigeonhole principle and Ramsey theory

For a sense of how these look as actual competition problems rather than topic lists, see our collection of math olympiad questions and the strategies in how to solve math olympiad problems.

Study from the Right Resources

The books that work for olympiad preparation are different from school textbooks, because they teach methods rather than drill procedures. A small number of titles cover most of what the early rounds need.

Books worth owning:

• Art of Problem Solving (AoPS) series: covers all four topic areas in depth, with a strong problem bank
• Problem Solving Strategies by Arthur Engel: the standard reference for advanced techniques
• Hungarian Problem Book series: particularly good for number theory and combinatorics

Online resources:

• Gonit App: step-by-step solutions and graded practice problems
• Brilliant.org: interactive courses on olympiad topics
• Khan Academy: useful for shoring up algebra and geometry foundations before olympiad work

More free options are collected in our guide to free math olympiad training online.

Solve Past Papers and Mock Tests

Past papers are the single most efficient preparation tool, because they show you the question style each round actually uses rather than what you imagine it uses.

Where to find past papers:

• Bangladesh Mathematical Olympiad: matholympiad.org.bd hosts past problems and announcements
• International Mathematical Olympiad: imo-official.org carries every IMO paper and the official results archive
• Olympiad books and problem forums: useful for solutions and alternative approaches

How to practise with them:

1. Set a timer so you build speed alongside accuracy.
2. Work the problem fully before reading any solution, even if it takes an hour.
3. Log which topic area each failed problem belonged to, then study that area rather than more random problems.
4. Discuss hard problems with peers or mentors to see approaches you would not have found alone.

That third step is the one most students skip, and it is the one that turns practice into progress. Our guide on how to improve problem solving skills for IMO goes deeper on building the habit.

Exam Strategy and Time Management

Both BdMO and IMO papers run to strict time limits, and a strong mathematician can still score poorly by spending three hours on one problem. Strategy is a separate skill from mathematics and it is worth practising on its own.

• Scan the whole paper first and start with the problem you can see a route into.
• Cap your time per problem in the early rounds, roughly 10 to 15 minutes, then move on and come back.
• Write your reasoning out in proof-based rounds, because a correct answer with no argument earns almost nothing.
• Reserve the last 10 minutes for checking arithmetic and finishing partial proofs, which often picks up more marks than a fresh attempt would.

Exam-day technique is covered in more detail in how to get full marks in maths olympiad.

Join a Math Olympiad Community

Olympiad preparation goes faster in a group, because most of the learning comes from seeing how someone else approached a problem you were stuck on.

• BdMO Facebook groups and the official forums
• Olympiad discussion communities on Reddit and Art of Problem Solving
• Gonit App discussion forums

How Bangladesh Compares with Other Countries

The structure is similar everywhere, which means preparation material from other national systems transfers well. The names and the number of stages are what change.

	Bangladesh	India	United States
Organising body	BdMO Committee	HBCSE	MAA
Entry round	Online selection round	IOQM	AMC 10 or AMC 12
Middle rounds	Regional olympiad	RMO	AIME
National round	National olympiad	INMO	USAMO or USAJMO
Training camp	National camp	IMOTC	MOP
Team size	6	6	6

If you are preparing from Bangladesh, Indian and American practice papers are genuinely useful, especially AMC and IOQM papers for the early answer-only rounds. Our guides to how to qualify for the IMO in the USA and the best math competitions in the world explain the alternatives.
