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 test is composed of four sections: two Math Sections, Critical Reading, and Writing Skills, and takes two hours and ten minutes to complete. Originally, each of the three sections was scored on a scale of 20 to 80 points, adding up to a maximum composite score of 240 points. This paralleled the SAT, which is graded on a scale of 200 to 800 for each section (the narrower range is to distinguish from which test a score comes and to denote less accuracy).
