Every group, every class
From counting mangoes
to the senior round.
Choose a group when you start. You can move to another class any time from the class chip at the top. Every class and subject has its own 20-week study plan, a starting-point check, at least ten practice quizzes and at least five mini mocks.
Kids
Number answers on a big number pad, solid shapes that turn round, and a 16-lesson picture course on shapes and geometry.
Small Starts
Timed mini mocks, picture activities and practice on the seven BdMO problem areas: number, algebra, geometry, counting and more.
Juniors
Olympiad-style maths and English with drawn figures, typed answers and questions in the style of the junior rounds.
High Flyers
Practice at SSC level, with a progress view that older students can read like a report card.
Trailblazers
HSC-level maths: trigonometry, calculus, complex numbers, counting and number theory, with ten timed mini mocks.
Seniors
Linear algebra, analysis, group theory, graph theory and harder number theory, in timed papers for the senior round.
Inside the app
Practice that explains,
not only marks.
A short quiz has three questions and a full paper has ten. Questions come as choices, tick boxes, a typed answer, things to put in order, pairs to match, or a drawn figure. The choices are shuffled every time, so position never gives the answer away.
A hint for every question
Each hint is written for that question and its topic. It tells you which step to think about, without handing over the answer.
A mistake book
Every wrong answer is saved next to the right one, topic by topic. Revision starts from what actually went wrong, the way a good teacher checks a khata.
Timer on or off
Run quizzes and mocks with or without the clock. Timed mocks allow 10 or 30 minutes to match the paper.
Read aloud
Every question and hint can be read out at slow, normal or fast speed. Automatic reading is on for Beginners and Kids and off for older students.
Stars and medals
A right answer brings a shower of stars, a wrong one a gentle shake. Finished quests earn bronze, silver or gold medals on the Compete shelf.
Up to six explorers
Brothers, sisters and cousins can share one phone or one PC. Each explorer keeps their own class, stars, saved work and settings.
Real screens
A quick look
inside.
Screens from the Android app. The web app looks the same on a bigger screen. Pip is drawn in code, so he stays sharp at any size, blinks on his own and watches your finger or mouse.
Puzzle corner
Space to think,
no marks.
Next to the practice for every level there are Sudoku and Killer Sudoku boards in five levels: easy, normal, hard, very hard and extreme. Boards are made on the device and always have exactly one answer. Below extreme, every board can be finished by reasoning alone, no guessing needed.
A hint works one square out and says why. The app also explains what each game is, how the two differ, how to play, how to finish and why they are worth the time.
Why puzzles sit next to olympiad practice
- Nothing here is timed or scored. A puzzle is for thinking in.
- Killer Sudoku cages add arithmetic to logic, the way olympiad problems do.
- Pausing hides the board and stops the clock, so a break is really a break.
- Solved levels are ticked off for each explorer.
A small taste
One question.
One small win.
Five sample questions, one from each of five groups. Pick an answer and see how the app replies: stars for a right one, a gentle shake and a reason for a wrong one.
This is a small activity written for this page. The full question bank is in the web app and the Android app.

For guardians and teachers
Private by design.
Yours to keep.
Tulx: Olympiad Prep is a study tool, not a service that collects data. On Android, everything a child does stays on the phone. On the web, progress stays in the browser unless a guardian chooses to save it to an account.
No ads, no tracking
There is nothing to buy and nothing to sell. The app shows no advertising and runs no analytics.
Works without internet
The Android app carries the whole question bank. It works on a bus, in a village, or with mobile data switched off. The web app only needs a browser.
A grown-up check
Removing an explorer, or creating an online account on the web app, asks a grown-up sum first and says what will change.
Honest about what it is. Tulx: Olympiad Prep is independent practice material made in Dhaka. It is not affiliated with, or endorsed by, the Bangladesh Mathematical Olympiad or any other organiser. Group names are the app's own labels for age and class ranges.
Read the privacy policy ↗Questions guardians ask
Before you start.
Short answers to the questions we hear most. The support page has more.
Is it really free?
Yes. Both the web app and the Android app are free. There are no ads, no in-app purchases and no paid version.
My child is in Class 4. Where do we start?
Choose Small Starts and then Class 4. Take the short starting-point check first, then follow the Today tab. The class can be changed later from the class chip at the top.
Does the web app save progress?
Yes, in the browser on that PC. If a guardian creates an account with an email address, progress is saved online as well and can be opened on another PC. The account can be deleted from inside the app at any time.
Can I use it on a phone and a PC?
The Android app and the web app are the same app, but they keep separate progress. Online accounts are available on the web app only for now.
Are the questions from real olympiad papers?
No. The questions are written for this app in the style and at the level of the olympiads students here sit for, from Class 1 to the senior round. Some practice sets were supplied by the project owner.
