Competition Format

Preliminary round

Sunday, September 28, 2025

Description: The preliminary round is open to all registered teams worldwide

Format:

  • A 60-minute Test (multiple choice and short question)
  • Each team member will individually attempt a set of test questions
  • Only the top two scores will be used to calculate the team’s total score

No proctoring is not required. The test will be conducted online with anti-cheating algorithms in place. Participants must use a laptop or computer with a camera and keep it on throughout the test.

Test Scope:

Middle School

The history and importance of computers, basic computer components and their functions (CPU, RAM, storage, input/output devices), an introduction to coding and programming languages (block coding, Python, JavaScript), algorithms and problem-solving in computer science, binary code and how computers process data, cybersecurity basics (passwords, encryption, and online safety), how the internet works (IP addresses, web browsing, and cloud computing), artificial intelligence and its applications, ethical issues in computing (privacy, data security, and digital citizenship), and real-world applications of computer science in robotics, gaming, and scientific research. 

You should be able to identify major coding languages and solve basic situational problems relating to computer science, as well as answering questions about major historical figures and developments. 

Ex: Imagine you are a codebreaker for Great Britain in World War 2. You have just solved an important problem with the Enigma machine. Which leader of British codebreaking and namesake of a famous “test” would you approach with your solution? 

A: Alan Turing  

High School

Computer architecture and hardware (CPUs, memory, storage, input/output devices), fundamental programming concepts (variables, loops, conditionals, functions, recursion, data structures), common programming languages (Python, Java, C++, JavaScript), algorithms and computational thinking (sorting, searching, efficiency, big-O notation), cybersecurity principles (encryption, network security, ethical hacking, privacy laws), databases and SQL, artificial intelligence and machine learning basics, software development methodologies (Agile, debugging, version control), how the internet works (IP addresses, domain name systems, protocols), and real-world applications of computer science in fields like robotics, gaming, finance, and medical research. 

Students should be able to write simple programs, describe standard algorithms, and recognize the purposes of major technologies without needing to implement advanced systems or perform professional-level coding. 

Ex: What computer science term describes how the performance of an algorithm changes as the size of the input increases? 

A: Big-O Notation
