As a certificate student, you would benefit from Bradford's online tutorial group approach. It's a supported form of team learning that has obvious advantages. I suspect that certificate students will study alongside MBAs in the tutorial group. After completing the certificate, Bradford alumni get careers support and are given a discount on completing MBA electives in a block-week format: http://www.bradford.ac.uk/management-and-law/alumni/benefits-and-services/
Students can count the certificate towards the MBA at a later stage.
