Feedback Request for dev challenge

I finished initial prototyping phase for this week’s development challenge and I’d like some feedback.

The project is a site where you can submit your algorithms to grade them.

There are a few views:
front page where a user can sign in or sign up.
main menu where a user can decide what to do next.
submit page where a user can add their solution.
profile page where a user can see their grades.
solution page where a user can see feedback for a given algorithm.
assessment page where a user can grade other people’s algorithms.

What do you think?
