Question: do you have to be smart to be in the air force?
Answer: The upshot is that an ASVAB score of 50 very roughly equates to an “average” IQ - so to get into any of the services above - if you are of average intelligence or better and graduated from high school, you should do just fine. A score of about 50 {give or take} is considered “average” for a H.S. graduate.
