Huge apologies to anyone confused about the changes this weekend to the published dates for the challenges. We noticed rather late in the day that the dates appearing in some places on the site differed from those published in the Teacher's Pack and it was the Teachers' Pack that was correct. Thanks to those of you who pointed out that the rules page showed a challenge being published in the middle of half term, and that the last challenge was apparently going to be published during the Christmas vacation. The correct dates are as follows

Notice that Challenge 3 lasts two weeks because of half term, and if you look at the points schedule for Challenge 3 (on the Challenge 3 page) you will see that the points are frozen throughout that week. I am really sorry for the confusion, mea culpa. Harry
