[substeps] Express your concerns to your parents soon after a problem occurs. (C) Talk to them first to make sure they understand why your teacher is yelling a lot. While not saying anything is necessary to offer your parents an understanding, if they understand why their yelling is so intense they may be much more willing to let you help. (D) However, parents are the first ones to intervene when you are being yelled at and when your parents are around and can get involved. Make sure you provide them with a reason why you need help.
