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.
The highest score you can get is 240. Your score is the index score of 190. Congratulations on doing so well as a freshman. The PSAT is the pre-test for the SAT generally given to 11th graders. In your case, you took the pre-test for the pre-test. You did very well, and you can be proud of your scores.
