Entry form

We know that some of you have had a little difficulty with the entry form, and we hope the changes we have made help those of you who were affected (without messing it up for the several hundred who have been able to enter already!) Let us know of any problems but please note the following:

If your password has o,O or 0 in it (or i, I or 1) please be careful when entering it.

Your username for the competition is the email address you registered with us so please use that when entering each challenge

You only need to resubmit if you have made an error in your submission

If our form acknowledging you r entry has backslash characters in it that you didn't type, don't worry. Our solution checker removes all the punctuation from our solution and yours (including spaces) before comparing them so it won't affect your mark.

We will be sending you feedback on your entries sometime tomorrow/wednesday so you can one last go if you didn't quite get it right.

All the best,
