What a teacher said about Bebras:
'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 ICT 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.'
