is this not Homework plagiarism. i am not sure why people can not use the regular resources 1)do prepare for the class befor e the lecture 2) follow the lectures in class room/virtual class room 3) follow up with the professor/tutor for questions
4) work in a study group (in a room /or virtual) for better understanding of material 5) do home works on own.
you make a good point. there could be a setting that asks the responder to not provide the answer. Sometimes kids just need more worked examples to understand how to do problems.
