A student entered a professor's office, visibly upset. "You said you would drop your lowest test score and my lowest score was 60. But that 60 was the best score on that test. Yes, the 60 was lower than the 65 and 75 I got on the other tests, but on the test I made 60, I learned more than anyone in the class."

"Oh me," sighed the professor, realizing the student was right. "What can I do to make this work out?"

What additional information would the professor need to treat everyone fairly and still drop the test score that is the lowest?
