It seems like if you sneeze at the DMV any more, you need to show POI. But for the written test it seems unlikely. After all, they assume you didn't drive there. When you go for the driving test they want to see it for the car being used for the test, but for written I don't think so. I'd bring the expired just in case, and not worry about it for now if it's impossible to get before going.

And good luck! We are rooting for her!
