Totally optional : Do the part where it challenge you to make it a mini golf game. You may want to do it after doing more basic tutorials.

When you are working on the mini golf, it is good to understand the X-Y coordinate system:

The App Inventor coordinate system is based on an X,Y grid where X is the horizontal axis and Y is the vertical axis. The upper left corner of the screen is location X=0 and Y=0, or (0,0). The x coordinates get larger as you move to the right and the y coordinates get larger as you move down. You may want to check this out https://www.youtube.com/watch?v=MrweyPm_6SY
