Quiz errors

[oneguy]

Quizzes in -->study-->on line quiz-->(anyquiz) gives error at attempting to take the quiz.  When I make my answer selection, it tells me the game is out of synchronization with server. 
If the quiz does launch, correct answers are marked incorrect. e.g. in http://www.nukeworker.com/quiz/quiz_info.php?quiz_id=1 the question "what is the decimal equivalent of 3/8?" was answered .375 but the quiz marked it wrong.  This occurs with 3 different users on 5 different computers. Is there anything I can look at here to clear this up?  The quizzes have worked here previously.

I haven't started the upgrades.

Sounds like 2 different issues, but perhaps not.  I don't know too much about the synchronization issue, I've never seen it before.  Might be a slow connection, or the site you are at might be cashe'ing things weirdly.

Could be related  to #1, but some of the questions are just fubar.
