is a question generator. Each topic has questions of three levels of difficulty, with the answers instantly available. Select either Chemistry or Physics to get started.

Currently I'm concentrating on creating the Chemistry topics, but there should soon be more Physics and Biology topics.

Is there a topic you'd like to have on the site? Then tweet me at @lazyrunner78

I'd appreciate it if you'd also tweet me if you find any errors or have any other suggestions.
