This project began on Monday November 28, 2011. I am posting here my progress as I complete each problem. I will not include any answers nor will I say what website I am getting these problems from. I intend for this to be a repository for what I’ve learned from this experience and not a searchable site for those looking for an easy answer.
Check out the highlights for a list of my favorite problems.
