Since I am now a two-time non-select reserve officer, when will the SELCON Board meet or publish the results?

Per the Promotion Board MOI*, you will soon receive a memorandum notifying you of your status though command channels.

The SELCON board should have been held immediately following the promotion board.

As I try to learn more about SELCON, I came across this link. I am not a lawyer, but I hope this information will help someone:

It won’t. Your mandatory retirement date isn’t until 20 years from when you commissioned per the reference I posted earlier. Nothing needs to happen now.

I went through the same thing, so my best advice is to finish up ILE. Not being educationally qualified is one of the biggest reasons for non-selection in the reserves, but the other side of that coin is that you see a lot more AZ selections once folks knock out the schooling.
