There were several things I did which may, or may not be considered for extra credit. I did the additional math problems as indicated in Part 5 of this assignment. I also did little things such as using lists and h1, h2, and underline fonts, etc. While not major items, they did provide me with additional practice with html basics. On a side note, I was surprised based on the amount of work involved in this assignment, it was worth the same 10 points as the previous much less involved assignments. I would have thought this would have been worth more points.
