If you score higher than 80 points, you will receive 1 bonus mark on a test of your choice. If you score higher than 110 points, you will receive 2 bonus marks on a test of your choice, or 1 extra mark on two tests. You can not get more than perfect on your test, however.
In order to prove what level you have reached, you must take a screen shot of your game. If you don't know how to do this, click here. Another option would be to take a photo of the screen with a cell phone camera and email it to me (but please make certain you let me know who you are in the email, or write your name on a piece of paper and hold it in the photo, or make the photo a selfie ).
