I kept my iPad 4 in my bag along with my books, however it was at the back of my bag where my calculator and my metal pencil case is.So I was wondering how strong the iPad 4's screen is.
BTW: The iPad 4 was in this case with something like the apple smart cover for the protection for the screen.
Here is the link to wha case I have.
