Not how my experience went. You read the books, you got the points, and (assuming you were doing well in every other aspect of the class), you got an A. But if you struggled with reading (as I did in school), you got poor grades despite the fact that your grammar, writing, and spelling were otherwise excellent. Very rarely did I get a teacher who rewarded reading; most of them punished my failure to read.
I hate to break it to you, but that almost certainly came from some karen that didn't want their individual son or daughter to be reading it. So they raised a big fuss with the teacher for principle to get the books banned in your classroom.
That's exactly what it was! She had twins at the same grade level and she didn't want them reading those books. This was in South Carolina, so this type of behavior was expected. The Karen's ruled South Carolina...
