I am a professor. If you are over 18, I cannot speak to your parents about your grades. It's a violation of privacy laws. If ANY parent tries to contact me (I've had over 8000 students and only 3 parents), they get directed to dean of students.
I routinely have 200 students in a class, and I would be aware of her grade.... Especially since she was special needs. You would check her to see if she was having translation issues... (Which having a sign language interpreter in class is out of date... I get a special mike with deaf students. I speak into it and they have an off-site live time captioner steam the class as a window on their computer so they can read every thing i say, but also take notes... It is also better for their privacy)
I tell students who score a certain level to drop. No guilt. What I have learned after 10 years is most students score in a range. No matter what, I can't change study habits. Those habits determine grades more than anything else. If you get a 70, 90% of my students could maybe get a 80 with hard work...maybe an 85, but not a 95 except on very rare occasions. It's not me,But how well you take notes, how well you focus, and prepare. If you have to get an A, it's not cruel to tell you to drop...I'm trying to be nice and tell you to try again. In my experience, it won't happen because you can't score that high given the odds.
I also hate extra credit. If you give it, it has to be fair. That is, every single student gets the same opportunity. When you give one student an assignment others don't get, you play favorites and that's not good.
