She (albeit slower than most) cooks really well. Ok, her knife skills aren't the best, because she's slow, but there really isn't anything else she CAN do.
We haven't found her 'special skill' yet. 
Tbh, I get your reservations. I really do, but WTF else is there for a DC with dyspraxia, dyslexia, dyscalculia etc?
She's not good with people, so people facing jobs are out (no retail or childcare), she's dyspraxic which rules out hairdressing (and probably the catering she has her heart set on), she isn't good with her hands to do a practical subject, she isn't any good at art, she is functioning at a 9/10yo's level in maths at 15, she really HASN'T got any other skills.
She eventually wants to do cakes, not main meals, so there will be far less knife work involved. She has got herself work experience in a local cake shop (best in town actually), and that's HER dream.
If she doesn't get the three 'C's, she can't do the course at college that she needs.
If an A* student gets an A, there ARE still medical schools they can go to.
It is hard on the A star / A pupils, but it WILL hit C/D pupils MORE especially in towns like mine.
Maybe not in every town, but in this town, if you miss out in a 'C', you're screwed.
