2 If I apply for the MSc and am unsuccessful would I have to submit a further application to be considered for the PGDip?
Not necessarily. Should an MSc application be unsuccessful, but the Admissions panel considers that the candidate is suitable for the PGDip, they are then able to make an offer for the PGDip without the need for an additional application. However, the admissions panel may request to see further evidence of suitability for the PGDip, such as an essay submission.
