Important update — we have moved to Google Meet

Because of a technical issue on our side, the competition will now be invigilated over Google Meet instead of Discord. Please ignore every earlier instruction about installing Discord or linking it to your CMC account — you do not need it, and nothing is expected of you now.

Your Google Meet link appears on your round in the waiting room once your slot is confirmed. Join it about 10 minutes before your slot with your camera and microphone on, and stay for the whole competition. Students sitting the exam under their own school's supervision should join the room their teacher gives them instead.
