Abstract: Improved techniques for dynamically controlling a program flow of a testing application. The testing application administers an exam on a user interface (UI). A state for each question is monitored, where the state includes a viewed, answered, or unviewed state. A question's state changes based on whether interaction is detected for that question. While the testing application is administering the exam, user input triggers a pause to the administration. A popup window is displayed to show a first list of instructions, a second list identifying exam questions having the “viewed” state, and a confirmation UI element. After the confirmation UI element is selected, the UI is modified by occluding the exam questions, by displaying a resume UI element, and by displaying a timing UI element. Later, the testing application continues the test's administration, but restricts access to certain questions.
