From Challenge 3 on your score counts to your final palcings in the leader board. There is no need to download the challenge on the dot of 3.15 as you have until midnight today to get full marks. We will release the challenge on twitter as a jpeg to give you another way to get it on the go. Speed and accuracy are both important, but accuracy is far more important than speed, so don't rush, and above all, dont hammer the server with requests or it will sulk again and it will stop talking to you.
Good luck,
Harry
