DD is 19 and got 1 A, 4 Bs and 3 Cs at GCSE. She went on to sixth form where she didn't pass the 1st year and had to leave, she went to another college to retake the first year (it was only maths as the other 2 subjects were 2 years) and failed again. She didn't get a chance to do any exams in the other subjects.
She works part time now and volunteers for childline. She says her volunteering has made her realise how much she wants to be a mental health nurse specifically to do with eating disorders.
I have said to her there are sooo many different ways you could get involved with that without being a nurse and she doesn't want to hear it, gets upset saying that she wishes I had faith in her etc. when I do!! She just isn't academic enough for uni.
I don't know how to offer her advice any more.
