Hi everyone! The countdown is on. Round 1B begins in under 24 hours. If you preferred to sleep instead of competing in round 1A (just like me!), then this round is for you! The top 1000 contestants from sub-round will advance to Online Round 2 and won't be able to compete in further sub-rounds.

I remind you that round will take place on Saturday, May 3 at 16:00 UTC at the site, that everybody knows.
