mintthins Can you ask school if they will give her a mock interview? I'm not going to suggest parental involvement because that probably won't go well...
When DS had to write a letter asking for a work experience place it was an eye opener. It is hard having to sell yourself but no-one is going to do it for you while you stand modestly on the sidelines. I really felt for him and offered to help but my input was not required other than providing the formal ending.
I am liking Y12, after last year I almost feel redundant. This time last year I was booking sixth form open evenings and comparing their prospectus and now all I'm doing is making sure he has change for the bus.
