What can my girlfriend do about her GCSE grade and Medicine?

My girfriend is not a UK citizen and she came to England 3 years ago. She took up Business, Maths and FM A-levels and then she decided to drop Bussines, for Chem and Bio to go to Med school. She had to take gcse English while taking the AS levels and now for the second time, she has recieved a 4.

She is panicked that she won't get into any uni because of this grade. To make things simplier she has been going to school in UK for 3 years up to the start of her med course (would she recieve an ofer) and has very good predicted grades. She was planing on applying to competitive unis, Oxford and Russel Group but now she has lost all hope.

What can she do from now on? She believes that by re-taking it she won't be able to achieve any higher and that she won't get any offers in order to take IELTS before the start of the course.

Edit: she is contextual
