Yikes,
Coach forgot to register dd's tests. So now she has to compete at a lower level since deadline is passed. Won't people say we sandbagged? She could really cream the others. I really don't need that reputation. What do you think?
If it's an in-house competition, the office should have the test on file, even if it wasn't registered with the ISI.
Your coach can contact the ISI to register the tests, explaining that it was an error.
You have to read the competition announcement to see if they allow skaters to skate a level higher than their highest registered test. Or ask the competition chairperson.
Honestly - your coach should be doing this legwork, not you.
