Logic Test --- Robert A. Kraus 2002

Answer each of the 8 questions with a letter from A to D.
The word "answer" in the test refers to YOUR answer, not some hypothetical "best" answer.
After choosing the 8 answers score the test by comparing each question with your answers.
Score 1 point for each question answered correctly, 0 otherwise.
Keep re-taking the test, trying to get the highest possible score.
(Of course you must know what the highest possible score is in order to correctly score
the last question!)
