I've had quite a few tests this semester that are like that! My professors call it the "upside down, backwards curve" :chuckle
I've remained above the curves on most but the absolute worst class is chemistry. 80% of the students in my lecture failed!
I came ONE POINT over passing! Thank goodness it's pass fail!
But yes, you'd think someone would be monitoring the TEACHER progress, not just the student progress.
I have since become an index card freak! :chuckle It's helped me get 2 test completed in Medical Terminology
with a perfect score on both tests and pass all of my A&P exams with over 80% as a grade. I study them when I'm watching the kiddos play in the bath, driving some where (dh driving of course) LOL and in between commercials when/if I ever sit long enough.
The taping lectures suggestion is a great one! I know many people who actually sit their recorder right on the podium in front of the professor! Don't be shy, YOU are paying them to teach you!
