As part of the International Astronomy and Astrophysics Competition, the pre final round question sheet has been released. Should questions regarding answers to the paper be closed, or at least have an 'answer embargo' of sorts until this section of the competition finishes in a week?
Yes, we should lock these posts until after the competition is done. If you see posts that needed to be locked for this reason, please flag them with a custom flag and reference which competition question the post is related to.
This applies only to new questions. Existing questions from before the competition began are still fair.
