When I get to the end of the "strengthen skills" quizzes, the program never awards XP or anything. After the last question, when I hit the "continue" button, the site doesn't do anything. So when I click on a different link, it says" Are you sure you want to quit, you will lose all progress."

Is this normal?

I am using new iMac with latest OS. My browser is google chrome.

This appears to be the only part of the site that does that to me.
