Q: What does International Junior Cybersecurity Olympiad: IP-Friendly Guide for Math & Physics Students cover?
A: What the IJCO is, how its Capture-the-Flag format nurtures problem-solving habits prized in Integrated-Programme Math & Physics.
TL;DR The International Junior Cybersecurity Olympiad is SIMCC's Capture-the-Flag competition for Secondary 1–JC2 (Grades 7–12) students, run onsite within the STEAM Ahead global finals SIMCC IJCO overview. Finals are delivered as a single four-hour CTF session covering cryptography, web exploitation, binaries and forensics-93 contestants from 11 countries took part in the Istanbul 2024 edition NCL IJCO 2024 recap. STEAM Ahead 2025 moves to Shenzhen (12–17 December) with NUS CeNCE/NCL workshops and invitations extended to Bronze-and-above winners in qualifying contests STEAM Ahead 2025 info pack.
Registration quick answer (Singapore): Follow the official IJCO site for the current year’s rules and registration route; countries run qualifiers and national rounds before the international finals. Check eligibility and dates at https://ijco.org/

Quick facts
Details
Organiser
Singapore International Mastery Contests Centre, with NUS CeNCE and the National Cybersecurity R&D Lab supporting training and challenge design SIMCC IJCO overview, STEAM Ahead 2025 info pack
Optional workshops (4–7 days) led by NUS CeNCE/NCL introduce Linux fundamentals, cybersecurity tools and practice CTF challenges so students arrive with a working toolkit STEAM Ahead 2025 info pack.
Capture-the-Flag final
Four-hour onsite CTF (CTFd platform) where mixed-national teams of about three contestants investigate pre-configured virtual machines, recover “flags”, and submit them to the scoreboard STEAM Ahead 2025 info pack.
Award ceremony & tiebreakers
Medals and team trophies presented during STEAM Ahead; if overall champions tie, a December 15 tiebreaker is held with buzzer-style questions STEAM Ahead 2025 info pack.
Challenge categories (2024 finals): cryptography, networking, red teaming, web exploitation, digital forensics-NCL prepared 54 tasks spanning these disciplines for the Istanbul event NCL IJCO 2024 recap.
Teamwork is strongly encouraged, communications are coordinated through contest chat channels, and all contestants must respect fair-play and bug-reporting rules set by SIMCC/NCL STEAM Ahead 2025 info pack.
3 Why IJCO suits IP Maths & Physics students
3.1 Shared mathematical underpinning
Classical ciphers drill modular arithmetic and frequency analysis - both appear in Binomial and Sequences & Series WAs.
Brute-force key-search problems grow as O(2n), an application of exponential functions and log-laws taught in IP Year 3.
3.2 Transferable physics skill-set
CTF write-ups demand the same free-body-diagram → algebra → justification workflow as mechanics derivations.
Time-boxed debugging tests the 1 mark ≈ 1.5 min pacing rule hammered into IP Physics timed practices.
Research on CTF pedagogy shows strong gains in analytical reasoning and “stickiness” of learning for novices IEEE/ACM study, and even highlights cognitive-bias traps to avoid CTF cognitive biases study.
4 Leveraging IJCO for Direct School Admission (DSA)
MOE lists “Infocomm (Cybersecurity)” under its official talent areas for DSA-Sec admissions, so IJCO achievements slot neatly into STEM-centric applications MOE DSA-Sec talent areas. IJCO medals showcase:
Algorithmic thinking grounded in real security puzzles.
Problem-solving under timed constraints (four-hour CTF finals).
Teamwork in STEM contexts (final teams typically comprise three contestants sharing workloads) STEAM Ahead 2025 info pack.
Portfolio tip: attach (i) the medal certificate, (ii) a one-page CTF write-up summarising tools and reasoning, and (iii) a reflection on learning - the same structure admissions panels often request for STEM talent areas.

Linux & tooling basics
Work through terminal fundamentals and Wireshark/Nmap labs to mirror the official training syllabus.
Device checklist: SIMCC recommends laptops running Windows 10+, macOS 12+, or modern Linux distributions with reliable internet access-the contest runs on CTFd and expects participants to install required tooling in advance STEAM Ahead 2025 info pack.
7 FAQs
Is prior coding required? The organiser strongly encourages contestants to pick up Python and C fundamentals before the onsite contest-training sessions cover the essentials, and recommended libraries include pwntools, python-nmap, scapy, pycryptodome, and more STEAM Ahead 2025 info pack.
Who can join? IJCO is open to Secondary 1–JC2 (Grades 7–12) students; invitations typically go to Bronze-and-above performers in partner cybersecurity contests such as NJCO and NJIO SIMCC IJCO overview, STEAM Ahead 2025 info pack.
When does the final take place? The 2025 STEAM Ahead schedule shows the IJCO finals block on 12–17 December in Shenzhen, with the CTF itself slated for a single afternoon (2–6 pm) and a tiebreaker window reserved on 15 December STEAM Ahead 2025 info pack.
