Whenever I give contests I feel extremely anxious. The last contest I gave I was only able to do A and after an hour I felt so much stress that I left the contest. 1 month later I upsolved the same contest up until E (inclusive). This happened to me many times before. While practicing I can often do <2000 problems without editorial but in contest I struggle with >1400 problems. Why is this so? How can I prevent this from happening? I don't want to be stuck in newbie
