<p>I have one further suggestion should you procede with writing your “letter of concern”. I think it might be best to avoid including specific concerns about the grade your D will get in the course (and the negative effect this would have on her GPA). This might be perceived as a parent just complaining about the grade their child recieves in a course. I feel you need to focus on the apparent inadequacies of the teaching your D and other students received from the professor and the issue of your D feeling she may have to take the course again in order to learn the information she should have learned from the course. Just a suggestion. Good luck.</p>
