"So, if it was known in previous semesters that a test bank was used, why such a large statistical aberration this time around?"

What evidence do we have for the large aberration?

Are there older reviews of the professor available online that say his tests are easy or that he reuses old test questions?

He showed slides of a normal distribution for the previous semester's results, vs a bimodal distribution for the current semester - that's the aberration I'm talking about.
