As a Teacher I think they have the responsibility to respond to student’s needs. May be you should talk to your counsellor. That’s what counsellors are for. I mean I think it’s ok for them to comment on what you should do and everything, but I think teachers should at least try to understand students and never respond with a I don’t know. If the class is too advanced for the student, I believe it is the teacher’s responsibility to infrom them that the class is too advanced for the student.
