As a parent in your position, I will say the following -
Most of the feedback about the FSCE has been kids not finishing the test. It was a LOT of questions in an unfamiliar format in very less time than usual. Your kiddo isn’t the only one who didn’t finish the paper so please don’t worry - if anything, it shows they’re all on the same boat!
Secondly, you did your best and so did your little one. Whatever has been done in the test can’t be changed now so focus on giving your child some relief and relaxation after all the 11+ stress - appreciate her efforts and think if this is how stressed you feel, imagine the stress inside her mind! It’s hard for kids to articulate stress but they do feel it too, especially if they sense their parent is stressed.
Lastly, focus on realistic options. Be open minded. Getting into a grammar school isn’t the be all end all. A lot of success depends on their home environment and parental support, which you are clearly providing ❤️
Not everybody will pass the test and that is OK. I feel the same stress and anxiety as you, I really HOPE my child passes BUT I am reminding myself that it’s not the end of the world if they don’t and that my job is to make my child feel confident, supported and hopeful about their future - not pass my stress on to them ❤️
Good luck and take it easy on yourself! x
