How to pass an exam without knowing the subject

How to pass an exam without knowing the subject

I was walking home from basketball and thinking about ignorance and obscurantism. I remembered the case of how my classmate in his fourth year was passing the test in nuclear physics, answering some of the questions both affirmatively and negatively at the same time. It looked like this:

- Does this transition belong to type E2?

- Yes... or no!

All the while he managed to laugh quietly. I held on as best I could so as not to give the game away. As a result, all five examinees got C's.

I respect him for inventing such a universal method. After all, you cannot make a mistake!

UPD: Pyotr seems to have got himself a disciple.

One fact never sank in: "Yes or no" is an affirmative sentence. Is Navalny a project of Pyotr's? A soldier of the famous "integrated army"?
