Thanks a lot folks! I have a LOT of questions to get the ultimate science quiz off the ground. Keep them coming - but I expect to be able to launch the quiz in the not-too-far-future. :)

 

I have the quiz engine ready, but I need to finish a new function that lets people save their progress. And we're going to have a ranking list, of course! This will be cool.

[modest]

Are you doing a time limit for each question?

And how about scoring individual categories - like when you stop it would say “your strongest subject is geology at 82% and your worst subject is anatomy at 16%”. That would be a neat aspect.

 

Can’t wait to see it - :xparty:
