She's not kidding

Student: How did I fail the exam? What did I need to pass?
Me: You need at least 60% to pass.
Student: But I did about half of the exam. That must be at least a B.
Me: Actually, if you only did half, the highest you could possibly get is a 50%, so that's less than 60%.
Student: Oh, ok.
