Funny that you mention that. When I was getting a master's degree in mechanical engineering, I took a Linear Systems Theory class that was so poorly taught that I had to go to MIT's open-courseware website and use their material to learn the course in parallel. You better believe that I gave my faculty advisor an earful about that clown.
This is the same instructor that lost my midterm exam and took two months to notify me that I got a B. I went into the final exam with a B, scored 85% on his final, and he notified me by e-mail that I my final grade was an F. I again complained to my faculty advisor and he called me at work to tell me to disregard that e-mail, my final grade is an A, and to call him on his cell phone immediately if the final grade on my report card comes out any different. He also asked me to not contact the instructor in any way. Weird.
My experience with that school (I'd rather not say what school) was very good except for that one instructor.
public or private school?
my daughter graduated from a top state university in a science major. She made decent grades in the classroom but not so good in the lab courses. In checking out this matter, for she has always been a good student, I learned the lab courses were all taught by graduate assistants and were all foreigners who spoke poor English. She could not understand the instructors. Checking further I learned that all of the graduate assistants were foreign - none were American. I wrote a formal complaint letter to the university , not just for my daughter, but for the fact they were discriminating against Americans. I received a nice letter in reply saying they would look into the matter. I never followed up, and neither did they. This was 30 years ago.
