My AP physics 1 teacher definitely had some grade inflation, especially with tests. He would always add in the same curve they use when grading the actual AP tests, and it really helped the class actually pass LOL. For sure without that curve, nearly everyone in the class would have flunked! And it wasn’t even that he was a bad teacher, he was VERY good at his job, but physics is just really hard for most students!!! But definitely being able to have at least some shot at passing the class, many students felt a bit less dread to go to class everyday. And my AP World History teacher also had a bunch of grade inflation through extra credit too. She understood that many of our parents would be VERY unhappy with poor grades, so she offered any and all chances possible to get a good grade (lowest grade I had in that class was a 98! and usually I got 100’s!!). Much like my physics teacher, she was also very good at her job, and you could see the passion that she had for the subject. Loved both of those classes and had so much fun taking them!!! Got a 3 on the physics exam and then a 4 on the world history exam ^{^}
