Ever taught first year calculus to a batch of pre med students? They're under pressure to score high, and feel like their entire future rides on every quiz, so tend to argue every point deducted. It's an incredible time suck, and really just demoralizing.

I had many profs take great joy in "failing" the pre-meds (a.k.a. letting the PhD and industry track students get better grades) for exactly this reason.

Hell, sometimes their parents argue about it.

The best defence against this I suspect is to have a clearly communicated, unambiguous grading scheme, but this can be difficult to do in an even handed way.

I had one undergrad prof whose policy was this: All incorrect answers get 0, no exceptions. Correct answers lose points for all steps not shown the way he had demonstrated.

There wasn't a lot to argue about, but none of us felt his approach was entirely fair.

That particular site doesn't exist here. There is a similar site, but not used very much.

Still, for what it's worth, have a look: https://www.meinprof.ch/uni/prof/1431

Vielen dank! Fwiw I totally believe you were telling the truth. :)

Because if there ever were a representative sample of how students feel about a professor, it’s ratemyprofessors.com.

Where else would it come from that is publicly available?

Nowhere, but many universities do have student feedback/evaluation forms that you get back after teaching a class, so a professor could know even if they weren't rated on a website.

I’ve seen a professor get cornered by a student and his parter who did not even take the class, sounding like a lawyer about three points or so on an exam they totally bombed, and it got very confrontational and uncomfortable. This sort of behavior is getting more common as the people who act like this often realize most people just bend and give them what they are asking.
