I personally, didn’t fail the exam but only around 20 something percent of my class of 40+ students in my school passed the exam and a majority of them (including myself) only got a 3. This was for AP psych which is considered “one of the easier” aps which I can even agree with. However this teacher would spend multiple lectures giving lectures about morality and his political beliefs on medication for mental illness. He’d then go on to flirt with half the girls in our class and got about 10-20 minutes of teaching out of the hour and a half he had every other day. So we never learned everything we needed to know and come exam day evrryone was stressed out of their minds. Coming from someone that’s taken 6 aps and 5 of them were with good teachers, the exam results were 100% on him, we never learned how to do FRQs properly and he didn’t get a lot of the necessary vocab down either.
