If you complete lessons successfully, you will receive not only STARS but COINS as well, up to a maximum of THREE. With one lesson you can only earn 3 coins, but if you don’t succeed in getting all 3, then you can try again to collect the rest.

When you complete a lesson you have to reach the following levels to earm coins and stars:


  • 60% = 1 coin/star
  • 75% = 2 coin/star
  • 90% = 3 coin/star
