> So taking the same test among the high IQ group getting a 95 gets you a C

This is the source of your confusion.

Your whole argument about the curve centers around the flawed and bizarre presumption that the curve has to center around a C. It doesn't always work that way, I don't think you understand some curves are different including the median score possibly being an 'F'. You're depending on some standardized curve, when in fact there's no requirement that be the case (and it often isn't). In the example with the footballers, every footballer gets an 'A' and with the random population the average gets an 'F' because the curves are compensated so that effectively there is an objective-like standard to maintain parity across like-performers.

>It's a probability distribution determined by scores from students. Nothing can be calibrated or adjusted here.

Of course something can be adjusted. you can make 'A' top 1%, B next 1%, C next 1%, D Next 1%, and fail the bottom 96% for instance. Not everyone has to grade to make sure most people pass, which apparently was the case at your selective school. At non-selective school the whole point is to fail every unfit person possible; it's even better for the school because engineering program was mostly bait to get these people into broader programs within the university.

You can go to the media, sue, or whatever. In my case it would look like this in the media "middle-class white man slightly less successful after being held to high standards" -- yeah that'll sell great! A few foreign students committed suicide after failing out of engineering paid for with their families 3rd world life savings and even then no one cares.
Good luck telling the judge that you didn't like the grade the professor gave you. Maybe your selective school mostly filthy-rich people with money to waste on lawsuits tying up the courts with cases that are meritless but wear down the college enough that they eventually relent.

>You understand that curving a grade is based on average scores right

Your curve may have been based around C being average. I have seen 'curves' where the average was F or D. I have seen courses where there is no curve as well, and isntead an objective system. A non-selective school can introduce a 'curve' where like performers get the same grade as in a selective school.

> The curve makes sure that only a small percentage of people get an A and guarantees a percentage of people fail.

Yeah our 'curves' weren't always like that. They were adjusted to compensate for non-selection present in our program. I.e. all people may fail or in a group of top performers no one may fail.

>Selectivity influences difficulty. Period.

Tell yourself your deranged and confused lie over and over, and tell me more about how you don't understand how different schools may grade differently (to objectively obtain same grade results as 'selective' school) even while maintaining SAME difficulty with a selective school.

> I thought we were talking about CS

Programming isn't equal to CS. Did you even study engineering or CS? Even chemical engineers program. These are all basic concepts you've missed, it's really hard to believe you have any experience at all in ABET accredited engineering program.

>ABET requires it in name, but no institution does this.

Maybe your institution acted fraudulently, but I saw people fail or incomplete a class for failing to meet ABET requirements. You're simply lying on this point to support your pathological obsession with denying selectivity does not confer difficulty.

>So they fail everyone in the class and the angry students take their outrage to the media? Then the parents come in and start a lawsuit which leads to a PR nightmare. Less students join the next year because nobody wants to be part of a school that failed an entire class.

No they fail almost everyone, the engineering rankings go up even further because any survivors are more impressive, and the rest filter into different programs. Everyone wins when almost everyone fails. The school uses engineering program as bait to draw people into other programs as much as anything. Failing almost everyone out is a win-win because it strengthens the bait and feeds money into other programs to broaden the school.

> The test is harder among the high IQ group. This is definitive man.

You have no understanding of an IQ test. It's meant to provide an objective outcome so that no matter the subset in a group taking the test, the measurement of the individual is the same. Taking the test with a group of fellow high-performers doesn't give you a lower IQ score. It's not harder no matter how selective you make the group taking the test. Universities can provide like feedback in grading. back to the analogy, the IQ score is the grade, get it?

>Selectivity influences difficulty. Period.

Selectivity doesn't confer difficulty. Period.
