It's been a while since I handled CT-ship solo. So when I fielded complaints over this kid or the other's poor aptitude for this or that other subject at my desk this afternoon, concluding in a request for me to discuss the dropping of subjects with the students in question, my response wasn't particularly wholehearted.
The subject I teach is compulsory for all students. I don't have the luxury of rejecting kids from my class if they display poor aptitude, or even attitude. Regardless of performance in class or their state of preparedness, when the time comes they will all sit for the final exam anyway. So pardon me for not enthusiastically assisting you in culling your flock to your satisfaction.
