I have many tests that I have created before I had Canvas. It is a HUGE pain to re-write every single question into the quiz section and every answer possibility. It would be very helpful if I could upload the PDF file of the original test that would appear on one side of the screen and then students could select the correct answers for multiple choice or answer essay questions on the other side of the screen while still viewing the PDF preview. Mastery Connect has had this option for years. While Canvas is much more user friendly than Mastery-Connect in other ways, it is still very much lacking in this highly convenient option when adding assessments.
