Lol, @GnocchiB ! I suspect she simply wasn’t trying until it mattered. To be fair, the 18 was a practice test score. She was a smart girl, but lazy at times. She was pretty unusual amongst all the students I’ve had. Apparently, she would never do anything until she was good and ready to do it. Sorry, no magic secret!
Hmmm, @Lindagaf sounds like someone I may or may not have given birth to! Sounds like it had a good ending (and that the parents probably were glad they hired a professional rather than nagging her to prepare for it themselves!).
