Yes, WSU is responsive and accessible on mobile phones and tablets through your web browser. However, please note that certain features are not fully available on touch devices. Interactive charts with complex hover interactions, drag-and-drop functionality, and some advanced question types that rely on precise cursor positioning may have limited functionality on touchscreens. For the complete experience with all features, we recommend using a desktop or laptop computer. Core features like practice questions, study tracking, and the WSU Assistant work well on all devices.
