I was wondering how you earn the various badges. I finished the modeling with modifiers course, but didn't get the badge for it.
Sometimes it glitches out. Try going to a video, marking it unwatched and watched again. If your exercise hasn't passed yet, I don't think it counts as done, either.
It's a little finicky after moving the site over. If you notice any bugs, feel free to contact cgcookie and tell them about it.
