my hasty internet research has yielded that one only needs to score 31 on ASVAB to qualify for enlistment in the army, which would indicate that ~70% of the people that take the test qualify. i've seen some sample tests and they look like they are roughly equivalent to technical college entrance exams. they appear to be easier than SATs and ACTs. but it's the internet so i can't say for certain what the ASVABs actually entail

but i don't think doing better than 30% of the people who take the ASVAB is equivalent to getting an associate degree
