Classroom Considerations

Although not important, know that players are greeted with a message containing the word "learnt" as they enter any Quiz feature.

For Quiz questions not answered correctly, a confused yellow face appears, scratching its head. Players will need to choose a new answer until they select the right one. For Quiz questions answered correctly, a gold coin is earned and a smiling face appears, along with audible applause. Players will need to tap an arrow beneath the icon to proceed to the next question. The next of three successive levels is unlocked after five questions. The player's score out of the total of 15 is displayed at the end of the series.
