Answer:
I can't think of any advantages to knowing your score.
Disadvantages of knowing your score - You're most likely to be average statistically...but does that matter? It doesn't tell you what you can or can't do, how successful you'll be, or what you'll face in the future. The total IQ score isn't really informative regarding almost anything. The exam is frequently used in clinical settings to assess areas of disability, competency, and so on...
(My opinion) :)))))
