Yeah, I got both lucky and unlucky at MEPS. Did the vision test fine, no problem, except me mishearing him saying that there are only D's and no O's, which was bogus because I was seeing O's and D's, but in the end I just said D's. For the depth perception test I was rushed. On top of being nervous as hell, since I am going for pilot, I completely botched it, but the tester passed me anyways. I could see which one popped out after awhile, but since I was being rushed by the tester saying "Come on, your taking all day" it was difficult to concentrate, so I guessed way before I could see it [mistake I know].
I say good because the guy passed me, and I know that after awhile of looking at it I could have seen the correct circle. I say bad because for awhile I was a bit down thinking that my eyes were not good enough, but now I know I was just being rushed.
Since everyone has said that you will no be rushed during the physical at OCS I am sure I will do well on all aspects of the test.
I have also read that at MEPS it is common for the depth perception test to not be set up correctly, so this could have also been the case.
