I had a teacher who had specific rules for exams when we wrote SQL statements:

- For a question worth 2 points, if you use the word "DISTINCT" when it wasn't needed, you lose 0.5 points.

- If you don't use "DISTINCT" when it was necessary, you lose all 2 points.

Oh yes, introducing a little game theory anxiety into exam questions sounds like a wonderful little torturing tool!
