Frequently Asked Questions

Do students work individually or in teams?

Students can either work by themselves or in a team of up to four.

Why do I need to collect parental consent forms for each student?

We need to ensure the safety of all students participating in the Bebras Australia Computational Thinking Challenge. As Bebras is an international challenge, your student’s information will be stored on its computer system in the Netherlands. At the end of each year, this information is completely deleted. Because the information is held overseas, all students must have parental permission to participate.

Why do we do this?
The information is stored for the school year so the teacher can log back in at any time to see their students results, compare them to the first round, or simply re-print a lost participation certificate.
Each student who receives full marks in the first round of Bebras will be placed on the online Honour Roll and will receive a special certificate. The parental consent form must be returned for your student to receive this.
All consent forms must be returned to CSIRO at:
CSIRO is committed to protecting your child’s privacy in accordance with the Australian Privacy Principles contained in the Privacy Action 1988 (Cth).

What is the Honour Roll?

The Honour Roll is awarded to students who receive full marks in the first round of the Bebras Australia Computational Thinking Challenge. Their name (with parental consent) is placed on the Honour Roll and a certificate signed by CSIRO’s Chief Executive, Dr Larry Marshall is sent out to the school.

Why is the Honour Roll only for the first round?

As the same questions are used in the second challenge and the solutions guide is readily available, only the the first round students who receive full marks will be eligible for the Honour Roll.

Some questions in the challenge aren’t loading for my students

We try to ensure that each challenge, and challenge question, is compatible on every device. However some school firewalls can block certain questions. We recommend talking to your IT department before the challenge just to be sure. You can also reach out to us with any concerns and we’ll do our best to support you.

Can students sit the challenge in multiple sittings?

As Bebras is a challenge, students have 45 minutes (or 60 minutes for year 3 & 4 students) to complete all the questions. This must be done in one sitting. Logging out does not stop the timer.

What is the achievement level breakdown?

Participation 0-59
Merit 60-68
Credit 69-101
Distinction 102-128
High Distinction 129-135

How are marks calculated?

There are 15 problems to be solved. These are presented under three levels of difficulty – Easy, Medium, Hard – each consisting of 5 questions. The questions get progressively more difficult as students advance upwards through the school system.
