This is an international competition run in over 60 countries, designed to get young people interested in Computing and Computational Thinking.
It is run every year and if you are in the top 10% in the country then you will be invited back for the second round.
You are given a series of questions, each given a difficulty label.
A is the easiest, C is the hardest.
You will get points for questions you answer correctly.
Each question is designed to test your ability of breaking down a problem into steps to get to a solution.
For B and C questions, if you're not sure, it may be better to leave it blank!
