Remington College

My Grand daughter attends Remington collage, I help her do her home work so i know its being finished. She has a problem with a teacher who harasses students on a daily and singles them out. It seams that the kids she dose this to are the less privileged. She is taking medical billing and coding and sometimes comes home crying because the teacher is so mean. The teacher fails her for her homework and test, i know she dose the home work cus i watch and help and im pretty sure she isnt refusing test to make a 0 on them. If she fails this class she has to pay the school extra money. I told her to ask to speak to the board and her teacher says shes not allowed to speak to any one higher than her. I dont know what to do about it, she tells me the teacher verbally assaults her and at times singles just her out. and my grand daughter isn't one to make something up, nor is she a defiant person. please someone look in to this.
