You should have a subject index on the left side of the screen. It's a searchable PDF.
If your calculator quits, don't give up!
Use the onscreen calculator.
Be aware of the time
Skip difficult or confusing problems and come back to them.
Don't spend too much time on a stumper or an unfamiliar concept. If you have time left over, you can spend more time in the equation book trying to figure it out.
Try to relax, breathe, and stay calm
You don't have to get every problem correct and you can review them later. Remember that you have solved much harder problems than these over the last four years!
