The Question Display Mode setting controls how questions appear to your test takers. You can choose between three display options, each with different implications for navigation, timing, and test security. Question Display Mode is a **Premium** feature. See [Payments and Credits](/payments-and-credits) for plan details. ## Display Modes Question display mode settings panel showing the three available options ### 1. All-at-once (Google Forms style) Candidates see all the questions at the same time, one below the other, like a Google Form. The timer applies to the **entire test**. Candidates can scroll freely between questions and answer them in any order. Candidate view of all-at-once display mode showing all questions on one page ### 2. One-by-one with navigation (Typeform style) Candidates see one question at a time and can navigate back and forth between questions. The timer applies to the **entire test**, not to individual questions. Candidates can revisit and change their answers at any point before submitting. Candidate view of one-by-one with navigation display mode showing a single question with Next and Previous buttons ### 3. One-by-one without navigation Candidates see one question at a time. Once they submit a question (by attempting or skipping it), they **cannot go back to it**. The timer is set **per question**, not for the entire test. Candidate view of one-by-one without navigation display mode showing a single question with Submit and Skip buttons ## Key Differences | Feature | All-at-once | One-by-one with nav | One-by-one without nav | | --------------------------------- | :---------: | :-----------------: | :--------------------: | | Timer scope | Entire test | Entire test | Per question | | Can go back to previous questions | Yes | Yes | No | | Custom instructions | Yes | No | No | ## When to Use One-by-one Without Navigation The no-navigation option is especially useful for test security. Candidates can view only one question at a time for a limited duration, which significantly reduces the opportunity to cheat. Each question has its own timer, so candidates cannot spend extra time on difficult questions by rushing through easier ones. ## How Timer Settings Change When you use **one-by-one without navigation**, certain test-level timer settings become unavailable. The timer behavior shifts to the question level: * **Duration**: You set the duration per question, not for the entire test * **Auto-Submit**: Each question auto-submits when its individual timer expires * **Must Submit By**: This test-level setting is replaced by **Cannot Start After** at the test level For more information on timer configuration, see [Timer Settings](/timer-settings). ## How to Set the Display Mode
