As you can see, with some planning, your excavation cost difference should be minimal. Footings: Cost for footings should be the same for a crawlspace or basement based on an average load bearing of the soil at 2000 psf (pounds per square foot). Walls: 4 foot high for crawlspace and 8 foot high for a basement.
But if your in-test-center score report says 156 and your actual final Praxis Core Math score is 14 points lower, it seems possible that there could be a mistake. The real issue is whether the 156 score is a mistake or the 142 score is a mistake.
This means the lowest possible score on a Praxis Core exam is 100 points, the highest possible score is 200, and the point range is 100. To calculate the unofficial score, the Praxis takes the percentage of correct responses and proportionally adjusts it to the 100 point range within the 100-200 scale.
