Create a fill-in-the-blank study aid from any PDF by using an iPad application called Quizdojo. Upload any PDF to Quizdojo and as you read through the content you can use the highlight, underline or strike-out tools to annotate as you might any kind of PDF document when making notes for yourself. You can also use a sticky note to make more detailed notes. QuizDojo summaries all your highlights and underlines and then creates a quiz based on them.

With the free version you can only create a limited number of questions (10) and upload a limited number of PDFs. With the paid version you can share out your quizzes with other QuizDojo users.

How you might use it:

• create study guide from class notes
• check reading comprehension
• have students share quizzes to see what others thought important
• use questions as discussion prompts

Once you take the quiz, you get a nice summary of the questions you missed, how much you improved, and suggestions for what you might want to review.

With the paid version you can share your quizzes with other users or share as annotated PDFs to evernote, dropbox, or by email.
