<h4 dir="auto">Issue Description</h4>
<p dir="auto">Hello, the Video Challenges are not being marked as complete.  I did the first four or so of computer basics and nothing was checked. I exited the browser, tried the first one two more times and it was still not marked as complete.  Then I tried the first one of JavaScript lingo, completed the quiz, but still no green check mark.</p>
<h4 dir="auto">Browser Information</h4>
<p dir="auto">Google Chrome, newest version<br>
OS X El Capitan</p>
<p dir="auto">It's not possible to mark some Computer Basics as completed. I tried to complete them many times. No success.</p>
