How about quizes and flash cards

Hello, I ´m a teacher and I like to make some flash card-sets en small quizes for my students. I like to set up a mobile site so they can learn wherever they are.

I looking for a simple interface. I´m just a amateur, I can´t really program.

I have seen some examples on the net like cobocards.com. This is the link: www.cobocards.com/en/tour/

This is een good example. But I want to be independent from other parties. So.... does anyone has a tip. Are there any real nice extentions for Joomla mobile? I like to hear it.

Thanks,
