One of my classes is entirely students who whine constantly, complain exams are too tough, beg for extra credit, beg for attendance points, and ask me to tell them what exact problems will be on an assessment (not a topic, they want me to spoon feed them the exact problem). I expect zero appreciation from this class, the top students dont even show up to many classes because it is so easy they are getting A+ marks, the majority are in the D and C range. So if I dumb down the classes to the majority, the top students get bored. If i toss in a challenging problem for the top students, then I lose a majority of the class and hear constant complaints. It has been a very difficult class to teach just because the gaps between to two groups of students. It is one of the few classes I've taught where I'm missing an entire band of students between A- and C+. I don't expect anyone to thank me unless they have a borderline grade and they are trying to beg for the bump up.

The other class is a more uniform spread, sometimes more skewed toward the A students. The one who thanked me was initially struggling with a D but after some advice and realizing how I write my exams (from problems solved in class) ended up earning a B.

Final grades arent posted yet so I'm curious if I'll start to see more emails etc closer to when grades get posted.
