You are able to scan an assignment that is two pages long but not double sided. If your assignment is long enough that GradeCam needs to print it on two pages, you are able to scan an assignment with two pages.
You are not able to design your own two page assignment. You are not able to create a break in the assignment to place on two pages. It would be if GradeCam needs to create two pages because the test would not fit all on one page.
Please let me know if you have any other questions.
