• Each section has its own timer that starts when you click “Begin Section.”
• Once you finish a section and move on, you cannot return to it.
• Within each section, you can move between questions freely.
• A pause button is available next to the timer — use it only if absolutely necessary. You will not be able to pause on exam day.
