No.
The grade awarded in a course reflects a students performance and mastery of the material. It is not compensation for being a classroom fixture. Disclosing that students are required to submit to a medical procedure before class starts does not change the nature of the exchange. If the class is a required credit for graduation, there is no choice.
As for no one being forced to attend the school, I doubt the application form includes a warning that students will be expected to submit to pelvic exams by fellow students. "Informed consent" requires information.
You are aware this class is training people to give medical exams?
Yeah, I got that.
As I said in a previous post, this will probably come to nothing. No university is going to put itself in the position of being seen as coercing students into submitting to an invasive examination.
