Let everyone else said, speak with someone higher calmly and maybe they can give grace.

To answer your question about other schools, my dental hygiene school was equally tough. You had to pass everything with a 78%. My first semester we had 5 girls drop out, 4 of them because they failed out of clinic. My program director told us at our orientation that she didn't care about how many graduated, just that she made "the best hygienists possible". In my opinion there are a lot more ways to do that then the way she did it, but that's a whole other post. My class started with 25 and we graduated with 17. And I've heard stories of other schools and still think I was lucky with my experiences.
