damn idiot chem teacher!

i think i would have your kid do some work and come up with all the back up docs. there has to be a paper trail. then get her to present the arguement. you just let her know that you have her back. if she triumphs over the idiot, then the lesson would be priceless. you are not going to come to her rescue everytime. she sounds like she is ahead of the learning curve anyways. if the chem idiot refuses to hear logical explanations, then you step in and drop the other foot.
