Students Expectations

I agree with Professor Grossman to a certain degree but then I start to disagree with him. I think this is because college students should not think that just because they show up for lectures and pass in their papers they should automattically get an A. But this is where I start to disagree with him because if a teacher sees a student showing up for the lectures and passing in their papers but are struggling and are doing everything that they can then their effort should be taken into account and reflect on their grade.
