No experience as far as borderline scores but DS did join DYS a few years back. Notwithstanding the language RE "minimum score," which remains the same, there had been many posters over the years who were accepted with below "minimum" scores, so your DS probably have as good a chance as before the change. I think that you might as well gather up any other above-level type assessments or stellar work samples and just go for it. Good luck.
