The professor is mostly a clinician and her goal is to have students know how to do things on rotations in another year in a way that the clinicians trust you know what you're doing. I understand the need to make people show they can do every step. I just don't understand the need to fail people who do not do every step under some arbitrary time constraint. Give them the grade their work deserved and absolutely require them to come back and correct anything they didn't do right the first time.

But failing them for not getting every step perfect just lumps someone who didn't pick a hoof perfectly in with someone who scared the horse or did something that could have gotten them or the horse killed. It tells students that there's no point in working hard, since you'll just have to do it again over and you're going to get a C no matter how hard you prepared.
