About

Each month, our team usually organize three or four online contests, which are called "Free Contest". These are free programming contests that everyone can join and compete. The purpose of these contests is for young coders in different regions in Vietnam to improve their coding skill with our high-quality problems.

All these contests are based on our humanitarian spirit, "using talent and strength to do the good things", where "good things" here means "to share knowledge and experience in a non-profit way".

Announcement of upcoming contests will be posted on our Facebook Page two days before contests. The usual duration for a contest is 3 hours, from 19:30 to 22:30 (UTC+7). Each contest usually has 5 problems. Contestants are allowed to submit multiple times. After a submission is submitted, it will be judged by our grading system (CMS), and the feedback will be sent to contestants. We also provide an online live scoreboard which allows everyone to observe during and after the contest.
