Why do professors scale marks and raise the marks of students that don't deserve it?

The problem is, the other students earned their grades as well. It is wrong to deny them of a passing grade when they understand the material to a level that the professor deems sufficient.

So you believe scaling a student from a 30% to a 65% is fair and the right of the student? What an awful entitlement complex you have. If the majority of the students failed with a 30%, they clearly demonstrated they did not understand the material, and if it wasn’t for department requirements and the fact the university needs students to take the course in the future, they would not have curved it. It isn’t about students who deserve the grade, unless you believe a 30% should be considered a pass in a course? </p>

Why do you keep insisting on relying on a completely arbitrary grading system that cannot account for wide discrepancies in test difficulty?

Grading is not entirely arbitrary; you must be a liberal arts major. If you haven’t noticed, grades are what decide if a student becomes a doctor, lawyer, engineer, mathematician, physicist, etc. </p>

Suppose you have two test scores of 70/100. One is for an exam in a “physics for poets” course where most people could already pass before even setting foot into the class. Another is for a upper division quantum mechanics course. Should the result be the exact same grade? Does that reflect equivalent amounts of understanding and proficiency in the respective courses?

Why not? If a student demonstrated they understand 70% of the material that is tested on, why do you believe they are entitled to a higher grade?</p>
