Here you go a scketch based on your brief where you can ask for any changes or make any suggestions. It's a modern layout, where the bow is made to look like a book, with the leafs through the line effect, what mixes the engeneering layout of the cog with the learning process-the position of the arrow also shows an upwards/positive direction... I'm not very sure about the text to be layed out in your logo but posted as in the brief.
If any sounds promising, even after contest ends submissions are possible for the 1st ranked designer.
Kind regards,
Claudia
