I have a math intensive course that requires students to solve problems numerically. I need to give quizzes outside of class time. My thought is to give the timed quiz with browser lockdown and then immediately go to another timed quiz (say 5-10 minutes) without lockdown browser so they can download a picture or a pdf of their work to canvas. Can this be done? Is there another better way achieve the goal of a more secure exam (students are great at getting around everything I've tried) and an opportunity to submit their hand written work?
