On the next two pages you will see a grid with mixed numbers and letters.
Your task is to mouse-click on the letters and numbers in an alternating,
ascending order as quickly as possible.
Click first on "A", then on "1",
then on "B", then on "2", then on "C",
then on "3", then on "D", then on "4",
etc... Until the end of the sequence at "Y".
Complete this task as fast as you can. You will be timed.
Do not click out of order. When you click on the correct square,
it will show a small green square in the lower right corner.
When you click on the wrong square, it will briefly turn red.
You will receive a 2 second penalty added to your final time for each incorrect click.
