My wife is going back to school to get her teaching certificate and is struggling with one of her courses. It is considered a core course for her program so she needs a C. Here most recent assignments all got C- grades so she is down to a C with four weeks left in the session. If she gets a C-, would she likely have to retake the course? The instructor has been difficult to work with and she is already getting help from some people. She emailed the instructor disputing the most recent grade she got but I'm not sure that will help. The amount of effort she has put into this particular class has been a lot and it would be devastating if she had to re-take the course.
