For my exams, I have to print out all of my notes because I have access to all of the other apps on my iPad. It would be great if from the app, there was a way to have a professor set a password and time limit to lock me out of the rest of the iPad and prevent me from closing good notes so I could use this during an exam. Then, when you are done with the exam or the timer expires, the lock will end and you can then close the good notes app and use the iPad as you normally would. Not sure if this is possible but I think this would help students who have open book exams immensely and help reduce paper usage!
