CHALLENGE 1

Don't forget that the first challenge will be posted after 3.15 tomorrow afternoon (Thursday 25th September). There is no need to all rush to download the challenges then. The servers are always crowded and you have over a day to submit for full marks, so it might be worth waiting for a bit. Before then make sure you have registered your team so you are ready to submit your answers. If you registered but didn't activate the account yet you need to do that now. If you don't know your password you can request a new one using the link on the left. If you want to register but you are not sure who will be in the team, or what the school postcode is then go ahead and register filling in what you can. Put a placeholder (e.g., "not known") in any field you can't fill in now and edit them later. Once you have submitted you need to wait a while before the feedback appears online (we are not emailing it this year). Once you have it you can submit again if you need to. Do ask if you have any questions. Good luck.
