Step 1: Mow your lawn. This will allow for you to see the unevenness and start with a "clean canvas."
Step 2: Determine the thatch level of the grass. It is near the surface of the ground. If it is too long (more than 1/2 inch), run a thatching rake or dethatching machine over the grass to loosen it, which will allow air and water to reach the roots.
Step 3: Create your lawn mixture. Take the sand, soil, and compost and create your lawn mixture. If compost is not available, make sure your top soil contains fertilizer nutrients. The mixture should be two parts sand, two parts soil, and one part compost. The sand helps to maintain the levelness of the yard because it doesn't compact easily.
Step 4: Dig up the divots. In the areas that have divots, take a shovel and dig further down... a few inches and then fill in the hole with the lawn mixture so that it's level. Then put the sod with the grass back on top.
Step 5: Spread the remaining mixture. Anything that is left over, spread over the remaining lawn to even everything out. Use a bow rake to help even it out and not create piles, which will cause the air to not reach the grass roots.
Step 6: Water the lawn. Plain and simple, water the lawn to help the mixture settle and jumpstart the nutrients in the soil.
Completing the above steps will help transition your lawn into a more even looking area. As the mixture settles, it might be something that you have to do more than once, but eventually your lawn will transform itself into one with beautiful curb appeal.
