My dyslexic daughter struggled with maths at school (as well as every other subject). She needed a C grade in Maths to pursue her hope to be a veterinary nurse.
I engaged a private maths tutor at great expense who, after a year of tutoring and 3 weeks before the GCSE exam, said my daughter would fail!
I decided we were not going to give up and I would help her myself, even though I am super- unconfident at maths. We worked for half an hour every evening on old exam papers.
