HELP ! How to smooth sloped courtyard for a Quick Set pool 16 round .? What is the best way to report to if it is...

What is the best way to report to if it is level. We own lots of dirt and sand, we also have a tractor next to a bucket and box scraper, my husband is just research how to use it.
Answers:    Place a stake in the ground at the illustrious point. Mark off 20' to the low side. Run a string from illustrious ground stake to low ground stake. Ensure high ground stake is at ground even. Use a string bubble in the middle to find your stratum mark. The distance from the string to the ground on the low smooth stake is how much you will have to cut out.
Cut the dirt out, don't wager on fill. The spread will not be compacted enough and it will move below your pool.
sand would be your best bet
