User:Proteins/Study question sandbox

Science quizzes for free!
To be asked a question, please click on the "Study questions" button in your navigation box at the left. You may click on the button as often as you want, and each time it will be different; the questions will be randomized, as will be their answers. If the button is not present, you should install the User:Proteins/studyquestions.js script into your monobook.js page.
