In this <a href="https://ctf.hkcert.org/index.html" target="_blank" rel="noopener">competition</a>, I have been invited by a friend who is currently studying in Secondary 6. As I have already guaduated from my Secondary School, we have to join the Open Category which is much more competitive than Secondary division and Tertiary division.</p> <p>It was a great experience and I would like to participate again next year.</p> <p><a href="https://ctftime.org/team/169874" target="_blank" rel="noopener">My Team</a></p> <p>Great shoutout to my teammate RedTea#9209</p>
