What is wrong with this picture? Why would 42% of the class fail this exam?
At some point, you have to examine why this exam has such a low pass rate and only an average of 70%.
There are people who usually honor exams who are in the 70s, so this is more than the usual story of lazy mediocre students bringing down the average.
Dr. B will definitely not have another supplemental and Dr. S will refuse to drop any questions.
Looks like it's time to ask why so many people are failing and what will be done to try to correct this.
