Manchester only have about 20 places according to their website. Don't know about Cardiff although Cardiff turned me down flat for the foundation year with 3 years of work experience, related AS Levels, the right GCSEs and an undergraduate certificate in natural sciences so I'm going to be big-headed and say it's going to be quite competitive. At both Kingston and Keele, you need to get 70% to pass the foundation year-Keele, no module can be below 70%! It's a bit scary!
