Not to sound salty or anything like that, but has the ASTB significantly changed format/difficulty in the past 8 years? When I was a MIDN, they didnt' even tell us much of anything about the test before we we took it. One day, they gave us the address of the local recruiter that administered the test and said go take it. I think there may have been an old study guide that just had the crazy pictures in it, but that was all we did. I never even heard of anybody failing it or sweating it. Do people fail it regularly? Is it somehow harder than back then? It seems like some of the posts on here are preparing like this was the ATP or something.
