How can candidates expand the screen during the examination?

To expand the screen during the examination, dragging a centerline to the left enables candidates to adjust the interface in a manner that optimizes their view of the examination materials. This action allows for a more comfortable and efficient review of questions and answers, which can be especially useful when balancing multiple panels or sections of the exam interface.

Depending on the specific software used in the examination, dragging a centerline may also help focus on particular areas of interest, such as detailed explanations or answer choices, enhancing the overall user experience.

While other options may offer screen adjustments, they may not provide the precise control needed to optimize viewing specifically for the examination interface. For instance, simply resizing the browser window may not alter the layout significantly, maximizing the application window could lead to loss of critical information displayed in a split-screen format, and relying on keyboard shortcuts can vary in effectiveness depending on the platform's limitations. Therefore, utilizing the centerline provides a tailored approach to enhancing visibility and usability during the exam.
