I can answer any questions related to any sort of problems with teachers, namely: grade issues, conflict-resolution, and anything related to those.
I have been in the public school system for 11 years (and I am on starting 12th). I have worked with an array of teacher personalities, and they have worked with me to make school be a healthy productive environment. Since 8th grade, the experience that I have accrued from solving problems with teachers is at the level that I don't need parent involvement. I have changed grades, from simple discussions, and I have fixed arguments from conversations.
