I didn’t retake the ASTB for the longest time because I had minimal weed usage and knew they wouldn’t take me even with ISEL scores.
Regarding your question about the March board, they did take some street apps because as one recruiter in my office told me, they have to “re-fill” OCS slots because people who were pro-rec y deny the offer for various reasons (sick, family, etc.). But hopefully we see good acceptance in June.
