## Note for Questions 10 and 11:

Questions 10 and 11 require you to submit drawings. We have a worksheet you can download and print. After you do the drawings on the worksheet, snap a picture of it with your phone or scan it and upload the image using the upload button under Question 11. The worksheet prints on a single sheet of standard letter-size paper.

If you have Photoshop or another drawing or editing program, you can do the drawings on your computer and simply upload the finished file without having to print it!
