If you get her to post on here then we can advise.
To get an offer it would help if she had high predicted grades from her teachers because the AS will mean they are likely to be concerned.
If she really wants to be a neuroscientist then she will need high A levels AAB +
Leicester is ABB.
She needs to get her scripts back and find out what went wrong, then start to improve. The good thing is she hasnt lost any marks because exams are linear so all exams and marks are at end of year 2. She could still get all A's, but she has to improve.
Revision books, tutor, youtube, lots of exam practice. If she works hard (maybe harder than she ever has), then she cna still make it.
If she doesnt get any offers, she still must get the grades and then use clearing or apply the following year.
This is in clearing at Cardiff. Neuroscience with a prelim year.

She needs to decide if she really wants it and if so she must commit to working hard and smart enough to boost her grades. Crying wont help her, dont quit , but get determined. Tell her she can still turn it round.
