Students applying for the Central St Martin's foundation course need to submit a portfolio and attend an interview. They are expected to have at least five GCSEs and two A-levels, one being art, at grade C and above. But if Francesca found it hard to impress the tutors, she is not alone. Alison Ostach, 20, a second-year womenswear student at Central St Martin's, said: "It is certainly the most difficult school I've tried to get into. I heard she had applied and we were all thinking there was no point in her coming here anyway. She has already got so much help in the business."
