Take part as a student
The 2025 Bebras challenge will take place in between 10th - 21st November.
How can I take part?
If your school runs the UK Bebras Challenge, your teacher can enrol you in September. When the challenge is live, and your teacher is available to supervise the event, they will give you your username and password. With these credentials, you'll be all set to participate in the UK Bebras challenge!
If your school does not run the UK Bebras Challenge but you want to take part, show your teacher this website and ask them if they will run the challenge. They can get in touch with us for more information.
If you are home educated, ask your parent or guardian to sign up here. You will be entered into a our home educated group and we will send out your sign in details in the week before the challenge starts.Prepare for the UK Bebras challenge
The best way to prepare for the Bebras challenge is by attempting to solve previous tasks. Tasks from previous challenges are available for practice, without the need for registration or logging in, on the challenges page of this site.
If your school is registered, your teachers will be able to access older tasks and challenges and assign them as quizzes for you to try.
Aim of the challenge
Your goal is to tackle as many tasks as possible within the 45-minute time frame to earn points. While the problems are tailored to your age group, they're designed to provide a challenge. Don't fret if you can't complete them all – it's rare for any student to solve every problem. If you find yourself stuck on a particular task, feel free to move on to the next one.
Difficulty levels
Tasks are categorised into three levels of difficulty: A, B, and C. Category A problems are the least challenging, while category C problems offer the most difficulty. Your score for each task is influenced by its assigned difficulty level.
Scoring
The scoring rubric is as follows
| Difficulty | Correct | Incorrect | Unanswered |
|---|---|---|---|
| A | +6 points | 0 points | 0 points |
| B | +9 points | -2 points | 0 points |
| C | +12 points | -4 points | 0 points |
