Not the scores. Only if you passed or failed.
I would assume that, as soon as the pass/fail is uploaded, we can see it. How long that takes to upload after the score is submitted to USNA by the test administrator is something I don't know.
If you're in a hurry to know, your RD can also tell you whether you passed or failed. If someone fails, only the RD has the ability to tell you the area(s) in which you need to improve. I don't know if they do this but would suspect they would at least in a general way -- i.e., "You need to do better in your mile run time." Your BGO can't tell you this b/c we don't know the minimums. An experienced BGO can probably guess what needs improvement if you provide your individual scores, but it would only be an educated guess.
