No definitely. I was a D grader back then as my RO don't like me. I complained to MOE and changed a RO. Then I applied for open posting. I managed to get another school which my new principal asked me to forget about the past. It is quite true when people say, "Don't stay at a place which don't value and appreciate you. Go to a place where people value you and appreciate you." I am working as hard as I used to be but I am happier at the new school. Good leaders don't look at your grades. They can see your strength which your old school leaders could not see. So, go to a new place which the new school cherish you. Don't suffer in silence, get out quickly. Start anew in a new school.
