Lesson is a lesson management platform that I built for the purpose of making my life as a Calculus teacher easier. It was originally a mercurial project hosted privately on Kiln - I've since decided to open source this project, change it to git, and move it here to GitHub.
Refactoring in progress...
I am currently in the process of refactoring the old code as much of it was written before I knew much about best practices (for example, there were no tests in the original project!). Since I use stripe for payment processing, I've not included any of my old mercurial commits in the move from Kiln-Github to protect my secret stripe-apis.
This transfer is a work in progress, check back for updates - I should probably be done sometime before the May 2014 but this is the busiest time of the year for teachers, so no guarantees!
