Thank you for giving so much information.
Nothing is for certain, but from what you have said it sounds as if you should have a very good chance of success.
We also speak Polish at home & she attends Polish school regularly.
Worth a mention, but it won't carry a great deal of weight if she was born in this country and has always been educated here.
She also had vision therapy for her eyes in the middle of last year and I am waiting for a report/letter from the Optician.
It's important to have the letter. How much weight it will carry depends on how serious the problem was.
does her being at a Private school lessen her chances?
does the date (i.e. earlier rather than later) make a difference?
