About Bebras

The Bebras Computing Challenge introduces computational thinking to students.
It is organized in over 60 countries and designed to get students all over the world excited about computing.
Last November over 400,000 students took part in the UK, and over 3 million worldwide.
Each participant answer questions that focus on computational and logical thinking.
It is completed online in your own school.

What teachers say about the challenge:
“I just want to say how much the children are enjoying this competition. It is the first year we have entered, and I have students aged 8 to 11 participating in my Computing lessons, with some of our older students also taking on the challenges. It is really helping to challenge their thinking, and they are showing great determination to try and complete each task! Also fantastic to find something that works on our iPads, as most puzzles of this kind are flash based.”

“Our students completed the challenge this morning, I just wanted to say thank you for running this. It’s a brilliant idea!”

2023 Bebras Statistics

2023 Bebras statistics

* As this is a challenge, the majority of older students are not expected to solve all of the problems in 40 minutes!
** Minimum score needed by students to be in the top 10% of each age group in 2023. These students are also invited, via their school, to enter OUCC.
*** Qualifying SVI students can take part in the normal Seniors and Elite OUCC Challenge or the beta OUCC SVI (10-14) challenge. The beta SVI challenge will use the same style as Seniors but with more age-appropriate questions.

Age Groups

The Challenge is available for the following age groups:

  England & Wales Scotland Northern Ireland
Kits* (age 6-8) Years 2 & 3 Years P2 & P3 Years 3 & 4
Castors* (age 8-10) Years 4 & 5 Years P4 & P5 Years 5 & 6
Juniors (age 10-12) Years 6 & 7 Years P6 & P7 Years 7 & 8
Intermediates (age 12-14) Years 8 & 9 Years S1 & S2 Years 9 & 10
Seniors (age 14-16) Years 10 & 11 Years S3 & S4 Years 11 & 12
Elite (age 16-18) Years 12 & 13 Years S5 & S6 Years 13 & 14

* Kits and Castors can enter individually or as a small team (up to 4)

Anyone within these groups can participate; it does not matter if they are language students or born mathematicians! The questions only require thinking skills.

The aim of the Challenges:

Solve as many problems as you can in 40 minutes.
You are not expected to finish!


The problems come in three levels of difficulty: A, B and C.
The "A" problems are the easiest. "C" problems the hardest.
You can find a problem's difficulty in the problem overview before you click on it.
The difficulty of a problem determines how it will be scored.

The scoring rules are 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

Our Carbon Footprint:

Our computing based system requires no paper to be posted between schools and our offices as everything is done electronically. The data centre that hosts UK Bebras obtains its electricity from wind farms. When the wind doesn't blow the energy comes from the grid but when it does blow there is more than enough for the servers and the excess is returned to the grid. The net result is that UK Bebras is using 100% wind energy overall. The heat from cooling the servers, when everyone is beavering away, is used to heat buildings in the neighbourhood.
