Crushers are calibrated in a test press. Pounded by high pressures, crushers don’t register peak pressure accurately because the flow of copper is slower than the change of pressure in the ...

Most of the time, grading on a curve boosts the students' grades by moving their actual scores up a few notches, perhaps increasing the letter grade.Some teachers use curves to adjust the scores received in exams, whereas other ...
How is the Grade Curve computed? Basically, what a grade curve does is provide a way to convert a exam's raw score (say, 38/50) into a grade-point score on the usual 4-point scale (i.e., A = 3.85 and above, A=3.50 to 3.84, etc.), using the overall statistical performance of the class to define the details of the conversion (i.e., setting the boundaries between A, B, C, etc.).
Grade inflation lowers standards, discounts achievement and hurts students in the outside world more than students realize. The grades in my example, like the grades of most colleges, are skewed toward the higher end of the curve. Average is a definition for C, but college averages based on grades assigned are no longer C.
