As a high school economics and history teacher, I wish you the best of luck. You probably already know this, but between now and tomorrow...
- Eat some good, healthy meals.
- Get lots of rest. I know, its hard, but try. A very dark room without blue lights in particular can be helpful in getting to sleep (cover those LEDs). To give an example of how times have changed, when I was in high school prepping for the AP US History test, our teacher recommended a glass of wine to help us sleep. I was 16. Nowadays, that would get that teacher arrested! Instead, maybe try warm milk or something else your parents approve of if getting to sleep is a problem.
- Lay out your clothes and goodies tonight so you aren't rushing around tomorrow. That includes a sack lunch.
- Arrive to school early so you aren't stressed rushing around at the last minute.
- Pray. It can't hurt!
- Finally, have a good time. Seriously. I tell my students that tests are chances to show what you know. Use this as a chance to really show off what you've learned.
Best of luck!
