What type of Mentor relationship is this. Is teh mentor a teacher from your school or like an enginer from some other company?
If the mentor is from another company or something like that, or ven at your school. Just write a letter to him teloing him/her how the team feels about his/her thoughts on th subjects at hand.
However, as Jane said, it is near teh end of the year, let the school year finish up and handle it over the summer.
You could always have a discussion witht eh mentors with a 3rd party administrator to find a happy medium between the two (or more) parties.
I hope this helps.
